Procedure

To a mixture of 0.102 g (0.0004 mole) of 2-chloro-9-(2-methoxy-ethyl)-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VI-40), 1 mL of N,N-dimethylacetamide and 0.037 mL (0.0006 mole) of iodomethane at 0 degrees was added 0.024 g (0.0006 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 0.087 g of 2-chloro-9-(2-methoxy-ethyl)-5-methyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-40) as an yellow solid.
