YieldReaction ConditionsOperation in experiment
Intermediate 57To a solution of 2-methyl-3-nitrophenol (15.3 g, 100 mmol) in DMF (150 mL) was added sodium hydride (60% in mineral oil, 2.6 g, 1 10 mmol) at 0C and the mixture was stirred for 30 minutes at room temperature. Methyl iodide (28.4 g, 200 mmol) was added and the mixture was heated to 80 C for 5 hours. Water (100 mL) was added and the mixture was extracted with ethyl acetate (3 times 100 mL). The combined ethyl acetate phases were dried over sodium sulphate and concentrated under vacuum to give a residue, which was purified by column chromatography on silica gel (PE:EtOAc = 5: 1 ). Evaporation afforded the title compound as a yellow solid (14.4 g).
With potassium carbonate; In N,N-dimethyl-formamide; at 20℃; for 14.0h; Methyl iodide (8.13 mL, 130.6 mmol) was added dropwise to a solution of 8 (10 g, 65.29 mmol) ,and potassium carbonate (18.05 g, 130.6 mmol) in anhydrous DMF (130 mL). The reaction mixture was stirred at rt for 14 h and quenched by the addition of H2O (250 mL). The aqueous phase was extracted with EtOAc (3 × 200 mL), the combined organic layers washed with water (100 mL), saturated sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and concentrated to give corresponding methyl ether as a colorless solid. Palladium on carbon (10%, 200 mg) was added to a solution of above product in EtOAc (130 mL). The suspension was stirred at rt for 6 h under a hydrogen atmosphere before it was filtered through a plug of celite and eluted with EtOAc (150 mL). The eluent was concentrated to afford 12 (8.59 g, 96% over two steps) as a colorless amorphous solid.

With N-chloro-succinimide; sulfuric acid; sodium sulfate; sodium nitrite; In water; acetonitrile; 4. Preparation of 4-chloro-2-methyl-3-nitrophenol A slurry of 4-chloro-2-methyl-3-nitroaniline (20.9 g), water (200 mL), and fluroboric acid (86 mL) was heated to boiling until almost complete solution took place, then cooled to 0-5 C. A solution of sodium nitrite (8.11 g) in water (20 mL) was then added dropwise to the above mixture, and then the mixture was stirred in the cold for an additional 30 min. The precipitated diazonium salt was filterd off and washed with a little cold water. The wet diazonium salt was added all at once to a hot (100-120 C.) solution of water (230 mL), concentrated sulfuric acid (115 mL), and sodium sulfate (35 g), and allowed to stir for 4 hr. The reaction mixture was cooled to room temperature and extracted with ethyl ether (700 mL in two portions). The combined ether extracts were washed with saturated sodium chloride solution, then dried over magnesium sulfate. Evaporation afforded crude product (17.5 g), which was purified by flash chromatography on silica, eluding with methylene chloride to afford 7.6 g as a yellow solid. The phenol was also prepared by the NCS chlorination of 2-methyl-3-nitrophenol, in a manner similar to that described in Oberhauser, J. Org. Chem. (1997) 62:4504-4506, as follows. STR72 2-Methyl-3-nitrophenol (25.5 g), N-chlorosuccinimide (44.5 g), and trifluormethanesulfonic acid (50.0 g) were combined in dry acetonitrile (500 mL) and allowed to stir under an atmosphere of nitrogen at 75 C. for 1.5 hr. The reaction mixture was cooled to room temperature, diluted with ethyl ether (650 mL), washed with water, 10% sodium bisulfite solution, water, and finally saturated sodium chloride solution. Evaporation of the solvent afforded a crude material which was flash chromatographed on silica and eluted with acetone:hexane (1:9) to afford 16.8 g as a yellow solid.

YieldReaction ConditionsOperation in experiment
69% With 2-(Dimethylamino)pyridine; acetic anhydride; triethylamine;palladium-carbon; In ethyl acetate; EXAMPLE 2 Synthesis of 4-acetoxyindole A suspension of 3.24 g of trans-6-benzyloxy-2-nitro-beta-pyrrolindino -styrene (prepared from 2-methyl-3-nitrophenol by a procedure reported in Organic Synthesis, Coll. Vol. 7, 34, 1990) and 648 mg of 10% pd/C catalyst in 30 ml of ethyl acetate was shaken under hydrogen atmosphere and at 50 psi, for 5 hours. To this reaction mixture were added acetic anhydride (1.4 ml), triethylamine (2.1 ml) and dimethylaminopyridine (324 mg). The resultant mixture was stirred for 1 hour at room temperature. The catalyst was removed over a layer of Celite and the filtrate was evaporated under reduced pressure to give an oily residue to which crushed ice was added. The resulting white precipitate was collected by filtration to give 1.2 g (69% yield) of 4-acetoxyindole: mp 97-98 C.; H-NMR (300 MHz, DMSO-d6)delta 2.32 (s,3H), 6.31 (s,1H), 6.71 (d,1H,J=8Hz), 7.05 (t, 1H, J=8 Hz), 7.28 (d,1H,J=8Hz), 7.32 (s,1H), 11.27 (s,1H).
