Triethylamine → N-{2-amino-5-[4-(6,6-dimethyl-5,6,7,8-tetrahydroquinazolin-4-yl)-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl]pyridin-3-yl}butanamide

Participants

Reaction Steps

To a solution of 5-[4-(6,6-dimethyl-5,6,7,8-tetrahydroquinazolin-4-yl)-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl]pyridine-2,3-diamine (32 mg, 0.077 mmol) and triethylamine (11 uL, 0.077 mmol) in tetrahydrofuran (1 mL) was add butyryl chloride (7.0 uL, 0.077 mmol), and the resulting mixture was stirred at room temperature for one hour. The reaction mixture was concentrated to give N-{2-amino-5-[4-(6,6-dimethyl-5,6,7,8-tetrahydroquinazolin-4-yl)-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl]pyridin-3-yl}butanamide crude product (50 mg). MS (EI) for C28H34N6O2: 487 (MH+).
