With triethylamine; In dichloromethane; | Example 110 N-[5-(5,6-Dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzoyl]-4-morpholinoaniline 4-Morpholinoaniline (0.286 g, 1.60 mmol), triethylamine (0.162 g, 1.60 mmol) and <strong>[37091-73-9]2-chloro-1,3-dimethylimidazolinium chloride</strong> (0.271 g, 1.60 mmol) were added to a methylene chloride solution (20 ml) of 5-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzoic acid (0.200 g, 0.535 mmol) and the resulting solution was stirred at room temperature for 12 hours. The reaction solution was poured into ice water and then extracted with methylene chloride. The extract was washed with water and then dried, and the solvent was removed by distillation. The obtained residue was purified by preparative thin-layer chromatography (hexane: ethyl acetate = 1:2) and then recrystallized from ether to obtain the titled compound (0.077 g, 0.144 mmol, 27percent). |

With 4,5-bis(diphenylphos4,5-bis(diphenylphosphino)-9,9-dimethylxanthenephino)-9,9-dimethylxanthene; sodium t-butanolate;tris-(dibenzylideneacetone)dipalladium(0); In toluene; at 90℃; for 16.0h;Product distribution / selectivity; | A.5 (5-Chloro-[l, 2, 4]triazolo[l, 5-a]pyridin-8-yl)-(4-morpholin-4-yl-phenyl)-amine[0332] A suspension of 8-bromo-5-chloro-[l,2,4]triazolo[l,5-a]pyridine (160 mg, 0.69 mmol),4-morpholin-4-yl-phenylamine (135 mg, 0.76 mmol), sodium-tert-butoxide (93 mg, 0.96 mmol), tris(dibenzylideneacetone)dipalladium (0) (13 mg, 13.76 mumol) and Xantphos (16 mg, 27.52 mumol) in dry toluene is heated at 90 0C in a sealed tube under a nitrogen atmosphere for 16 hours. The reaction mixture is evaporated to dryness and the residue partitioned between dichloromethane and 10 % aqueous citric acid. The organic phase is further washed with water (Ix) and brine (Ix), dried over magnesium sulfate, filtered and evaporated. The solid residue (207 mg) is purified by flash chromatography (silica gel, dichloromethane/methanol 97:3) affording the title compound (70 mg) as a solid. |

88% | With toluene-4-sulfonic acid; In 1,4-dioxane;Heating / reflux; | A mixture of <strong>[499195-60-7]ethyl 4-(2-chloropyrimidin-4-yl)benzoate</strong> (26.15 g, 99.7 mmol) and 4-morpholinoaniline (23.10 g, 129.6 mmol) was suspended in 1,4-dioxane (250 mL). p- Toluenesulfonic acid monohydrate (17.07 g, 89.73 mmol) was added. The mixture was heated at reflux for 40 h., cooled to ambient temperature, concentrated then the residue was partitioned between ethyl acetate and 1 : 1 saturated sodium bicarbonate/water (IL total). The organic phase was washed with water (2 x 100 mL) and concentrated. The aqueous phase was extracted with dichloromethane (3 x 200 mL). The material which precipitated during this workup was collected by filtration and set aside. The liquid organics were combined, concentrated, triturated with methanol (200 mL) and filtered to yield additional yellow solid. The solids were combined, suspended in methanol (500 mL), allowed to stand overnight then sonicated and filtered. The solids were washed with methanol (2x 50 mL) to give, after drying, ethyl 4-(2-(4- morphonlinophenylamino)pyrimidin-4-yl)benzoate (35.39 g , 88%). 1H NMR (300 MHz, J6-DMSO) delta 9.49 (IH, s); 8.54 (IH, d, J= 5.0 Hz); 8.27 (2H, d, J= 8.7 Hz); 8.10 (2H, d, J= 8.7 Hz), 7.66 (2H, d, J= 9.1 Hz); 7.38 (IH, d, J= 5.0Hz); 6.93 (2H, d, J= 8.7 Hz); 4.35 (2H, q, J= 6.9 Hz), 3.73 (4H, m); 3.04 (4H, m); 1.34 (3H, t, J= 6.9 Hz); LC-ESI- MS (method B): rt 7.5 min.; m/z 404.1 [M+H]+. |

80.4% | With trifluoroacetic acid; In iso-butanol; at 100℃; | General procedure: To a solution of 3a-r (1.50 mmol, 1 eq) and 6a-b (1.50 mmol, 1eq) in 2-BuOH (8 mL) were added TFA (2 mL). The slurrywas heatedto 100 C for 2e3 h. The reaction mixture was allowed to cool toroom temperature and was neutralized with a saturated aqueoussodium bicarbonate solution. The mixture was then extracted withethyl acetate (50 mL) three times. The crude was purified by flashchromatography with 25:1 (v/v) dichloromethane - methanol. |
