Dimethylamine, hydrochloride → HCID 86723806, compound

Participants

Reaction Steps

To a solution of 4-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-6-methyl-5-oxo-2,3,4,5-tetrahydro-1,4-benzoxazepine-7-carboxylic acid (130f, 0.17 g, 0.38 mmol), dimethylamine hydrochloride (47 mg, 0.57 mmol) and DIPEA (0.25 g, 1.90 mmol) in DMF (10 mL) was added HATU (0.29 g, 0.76 mmol). The mixture was stirred at room temperature under N2 for 5 hours. To the reaction mixture was added H2O (30 mL). The mixture was extracted with EtOAc (2×20 mL). The combined organic layers were washed with brine (4×30 mL), dried over Na2SO4, and concentrated under vacuum. The residue was purified by column chromatography (petroleum ether/EtOAc, 1/1) to give 4-{[2-(benzyloxy)-4,6-dimethylpyridin-3-yl]methyl}-N,6-dimethyl-5-oxo-2,3,4,5-tetrahydro-1,4-benzoxazepine-7-carboxamide (130 g, 0.17 g, 94.6%) as a white solid.
