Procedure

3-[(5-Amino-2-chloro-pyrimidin-4-yl)-cyclopentyl-amino]-2,2-dimethyl-propionic acid ethyl ester in DMF was heated to 140° C. for 2 hours. Solvent was evaporated in vacuo, ethyl acetate added, and the resulting solid filtered and dried under vacuum to give 2-Chloro-9-cyclopentyl-7,7-dimethyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one
