---|---|---|
98% | To a solution of 2-amino-6-methoxybenzoic acid (9.0 g, 53.8 mmol) in THF (270 mL) was added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (23.7 g, 123.7 mmol) and hydroxybenzotriazole (23.9 g, 156.0 mmol). The mixture was stirred at rt for 30 min, then N-methylmorpholine (18.2 g, 180.3 mmol) and NH4OH ( 50 vol % in H2O, 36 mL) were added. The reaction mixture was then stirred for 18 h at rt. After that time the reaction was concentrated under reduced pressure and diluted with ethyl acetate (600 mL). The organic phase was washed with brine (2×100 mL), dried over Na2SO4 and concentrated under reduced pressure to give 2-amino-6-methoxybenzamide (8.80 g, 98%) as a light yellow solid: 1H NMR (400 MHz, DMSO-d6): δ 7.55 (br s, 1H), 7.29 (br s, 1H), 7.01 (t, J=8.4 Hz, 1H), 6.36 (br s, 2H), 6.30 (dd, J=8.4, 0.8 Hz, 1H), 6.17 (dd, J=8.0, 1.2 Hz, 1H), 3.76 (s, 3H) | |
65% | To a stirred solution of 2-amino-6-methoxy-benzoicacid (3.00 g, 17.9 mmol) in THF (90 mL), EDCI (7.89 g, 41.1 mmol) and HOBt (7.95 g, 51.9 mmol) were added and stirred at room temperature for 30 minutes then N-methylmorpholine (6.15 g, 60.0 mmol) and aqueous 50% v/v NH4OH (12 mL, 171.4 mmol) was added. The mixture was stirred for 16 hours at room temperature. The solvent was removed under reduced pressure and the residue was extracted with ethylacetate (4*100 mL), the combined organic phase was washed with water and brine, and dried over anhydrous sodium sulfate; the solvent was evaporated to give 2-amino-6-methoxy-benzamide as an off-white solid. Yield: 1.90 g, (65%) | |
65% | Example 67 Preparation of 2-(3,5-Dimethyl-4-(2-(pyrrolidin-1-yl)ethoxy)phenyl)-5-methoxyquinazolin-4(3H)-one To a stirred solution of 2-amino-6-methoxy-benzoic acid (3.00 g, 17.9 mmol) in THF (90 mL), EDCl (7.89 g, 41.1 mmol) and HOBt (7.95 g, 51.9 mmol) were added and stirred at room temperature for 30 minutes then N-methylmorpholine (6.15 g, 60.0 mmol) and aqueous 50% v/v NH4OH (12 mL, 171.4 mmol) was added.
