反応手順

To a mixture of 1-acetyl-piperidine-4-carboxylic acid (822 mg, 4.8 mmol, 1.2 eq.), EDC (920 mg, 1.2 eq.), HOBt (648 mg, 1.2 eq.) in DCM (15 mL) was added TEA (1.3 mL, 2 eq.) and 1,4,5,6,7,8-hexahydro-pyrrolo[3,2-b]azepine (550 mg, 4 mmol). The mixture was stirred at rt for 2 days. The reaction was diluted with DCM, washed with water, sat. NaHCO3, brine, dried and concentrated. The residue was purified on a silica gel column to give 1.1 g of 1-[4-(5,6,7,8-tetrahydro-1H-pyrrolo[3,2-b]azepine-4-carbonyl)-piperidin-1-yl]-ethanone as a white solid.
