실험 절차

A mixture of 0.05 g (0.15 mmole) of 2-chloro-9-cyclopentyl-7,7-difluoro-5-propyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-144), 0.04 g (0.17 mmole) of 4-amino-N-(tetrahydro-pyran-4-yl)-benzamide, 0.04 g (0.22 mmole) of p-toluenesulfonic acid monohydrate and 4.0 mL of 2-propanol was heated at 160 degrees for 2 hours in a microwave reactor. The cooled mixture was concentrated under reduced pressure. The residue was diluted with dichloromethane and washed twice with saturated aqueous sodium bicarbonate solution. The aqueous phases were extracted with dichloromethane, and the combined organic layers washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography eluting with methanol-dichloromethane (gradient, 0:100-25:75), to give 0.020 g of 4-(9-cyclopentyl-7,7-difluoro-6-oxo-5-propyl-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-N-(tetrahydro-pyran-4-yl)-benzamide (I-149).
