Procedure

A mixture of 0.20 g (0.58 mmole) of 2-chloro-9-cyclopentyl-7,7-difluoro-5-propyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-144) and 0.12 g (0.87 mmole) of 4-aminobenzoic acid in a 1:4 mixture of 10 mL of ethanol and 1M hydrochloric acid was heated at 100 degrees for 18 hours. After cooling, the precipitate was collected by filtration, washed with water and dried to give 0.21 g of 4-(9-cyclopentyl-7,7-difluoro-6-oxo-5-propyl-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-benzoic acid (I-144).
