Participants

Reaction Steps

To a mixture of 0.14 g (0.0005 mole) of (rac)-2-chloro-9-(2,2-dimethyl-cyclopentyl)-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VI-59), 0.047 mL (0.00075 mole) of iodomethane and 1 mL of N,N-dimethylacetamide at 0 degrees, was added 0.03 g (0.00075 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 0.130 g of (rac)-2-chloro-5-methyl-9-(2,2-dimethyl-cyclopentyl)-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-59) as a yellow solid.
