Procedure

The mixture of 0.08 g (0.22 mole) of 2-chloro-7,7-difluoro-5-methyl-9-(2-phenoxy-ethyl)-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-304), 0.070 g (0.26 mole) of 4-amino-3-methoxy-N-(1-methyl-piperidin-4-yl)-benzamide, 0.062 g (0.33 mole) of p-toluenesulfonic acid monohydrate and 4 mL of isopropanol was heated in a pressure 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, 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, 100:0-20:80) gave 0.051 g of give 4-[7,7-difluoro-5-methyl-6-oxo-9-(2-phenoxy-ethyl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino]-3-methoxy-N-(1-methyl-piperidin-4-yl)-benzamide as a white solid (I-304).
