Procedure

To a mixture of 0.28 g (0.001 mole) of (rac)-2-chloro-9-cyclopentyl-8-methyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one, 2 mL of N,N-dimethylacetamide and 0.093 mL (0.0015 mole) of iodomethane at 0 degrees was added 0.06 g (0.0015 mole) of 60% sodium hydride in oil. The mixture was stirred at ambient temperature for 1 hour, then 10 mL of water was added. The precipitate collected by filtration to give 0.278 g of (rac)-2-chloro-9-cyclopentyl-5,8-dimethyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-3) as an yellow solid.
