Procedure

To a mixture of 0.09 g (0.0003 mole) of (rac)-2-chloro-9-cyclopentyl-7,8-dimethyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VI-41), 1 mL of N,N-dimethylacetamide and 0.028 mL (0.00045 mole) of iodomethane at 0 degrees was added 0.027 g (0.00045 mole) of 60% sodium hydride in oil. The mixture was stirred at ambient temperature for 1 hour, then 20 mL of water was added. The precipitate was collected by filtration to give 0.092 g of (rac)-2-chloro-9-cyclopentyl-5,7,8-trimethyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-41) as an yellow solid.
