YieldReaction ConditionsOperation in experiment
76.66% With ammonia; In tetrahydrofuran; at -78℃; for 3h; To solution of 3, 5-dichlorothiophene-2-sulfonyl chloride (6.2 g, 23.70 mmol) in THF (10 mL), saturated ammonia solution in THF (60 mL) was added at -78 C. The solid precipitated out and evaporated to dryness and the crude triturated with pentane to obtain the title compound, lnt-B-2.15 (4.4 g, 76.66 %). LCMS ESI(-ve) (m/z): 240.0 (M-2).
68% With ammonia; In 1,4-dioxane; water monomer; at 0℃; for 0.5h; (143e) 5-Bromothiophene-2-sulfonamide 5-Bromothiophene-2-sulfonyl chloride (0.30 g, 1.2 mmol) was dissolved in 1,4-dioxane (2 mL). The resulting mixture was stirred at 0C, and 28% ammonia water (4 mL) was added thereto. The resulting mixture was stirred at 0C for 30 min. The reaction solvent was evaporated under reduced pressure, and water was added to the residue. After extraction with methylene chloride, the organic layer was washed with water and brine, and then dried with anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to obtain 0.19 g (yield: 68%) of a crude product of the title compound as a white solid. 1H-NMR (400 MHz, CDCl3) δ ppm: 7.42 (1H, m), 7.06 (1H, m), 5.02 (2H, s).
With ammonia; at 15℃; for 0.2h; To a solution of 5-bromothiophene-2-sulfonyl chloride (2 g, 7.65 mmol, 1 eq) in ammonia (1.95 g, 115 mmol, 1.92 mL, 15 eq). The mixture was stirred at 15 C for 0.2 hour. TLC (petroleum ether/EtOAc = 3/1) indicated 5-bromothiophene-2-sulfonyl chloride was consumed completely and new spot formed. The reaction mixture was concentrated under reduced pressure to give a residue. The mixture was dissolved in EtOAc (20 mL), and then strried at 20 C for 5 mins. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure to give desired 5-bromothiophene-2-sulfonamide (1.5 g, crude) as a white solid.

With sodium hydroxide; In water; N,N-dimethyl-formamide; at 130 - 150℃; for 0.75h;Microwave irradiation; INTERMEDIATE 29; This shows the preparation of 5-[(3-chlorophenyl)thio]thiophene-2-sulfonamide,To a solution of 3-chlorobenzenethiol (87 mg) and 5-bromothiophene-2-sulfonamide (121 mg) in DMF (1 mL) was added aqueous 2 N sodium hydroxide solution (100 μL) and water (1 mL). The reaction was heated in a CEM Discover microwave for 15 rain at 130 C, then for a further 30 min at 150 C. The dark solution was partitioned between diethyl ether and water, and the organic phase was dried over sodium sulfate and concentrated in vacuo. The crude residue was purified by RPHPLC (Xterra, 5% to 95% acetonitrile in TFA (0.2% aq.)) to give the title compound 5-[(3- chlorophenyl)thio]thiophene-2-sulfonamide (35 mg).1H NMR (300 MHz, DMSO) δ 7.79 (s, 2H), 7.56 (d, 1H), 7.47 (d, 1H), 7.44 - 7.35 (m, 3H), 7.30 - 7.26 (m, 1H).

The N2 purge was stopped and the reaction mixture was sealed and heated with a preheated oil bath at 100 C. overnight. The reaction mixture was filtered and the filtrate was partitioned between saturated NaHCO3 and EtOAc, the layers were separated, and the aqueous layer was extracted again with EtOAc. The combined organic layers were dried (MgSO4), filtered, and evaporated in vacuo.
