실험 절차

A mixture of 0.08 g (0.25 mmole) of 2-chloro-9-cyclopentyl-7,7-difluoro-5-methyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-20) and 0.112 g (0.30 mmole) of 4-amino-N-[1-(3-methanesulfonyl-propyl)-piperidin-4-yl]-3-methoxy-benzamide and 0.072 g (0.38 mmole) of p-toluenesulfonic acid monohydrate in 3 mL of isopropanol was stirred in a sealed tube at 140 degrees overnight. After cooling, dichloromethane and saturated sodium carbonate were added. The mixture was extracted twice with dichloromethane. The combined organic layers were washed three times with sodium carbonate solution, three times with brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. Purification by silica gel chromatography, eluting with dichloromethane-methanol (gradient, 100:0-85:15) gave 0.11 g of 4-(9-cyclopentyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-N-[1-(3-methanesulfonyl-propyl)-piperidin-4-yl]-3-methoxy-benzamide (I-76) as a white solid.
