Procedure

A mixture of 0.0642 g (0.194 mmole) 2-chloro-9-cyclohexyl-7,7-difluoro-5-methyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-246), 0.0542 g (0.29 mmole) of toluenesulfonic acid monohydrate, 0.0451 g (0.194 mmole) of 4-amino-N-(2-dimethylamino-ethyl)-3-methoxy-benzamide and 1 mL of isopropanol was heated in a sealed vessel at 140 degrees for 16 hours, cooled and concentrated under reduced pressure. The residue taken up in ethyl acetate and washed successively with 50 mL of saturated aqueous sodium bicarbonate, 50 mL of water, 50 mL of brine. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography, eluting with acetonitrile-methanol-triethylamine (85:15:1) to give 0.0743 g of 4-(9-cyclohexyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-N-(2-dimethylamino-ethyl)-3-methoxy-benzamide (I-253) as a white solid.
