Procedure

A mixture of 0.20 g (0.66 mmole) of 2-chloro-9-cyclopentyl-7,7-difluoro-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VI-20) and 0.11 g (0.79 mmole) of 4-aminobenzoic acid in a 1:4 mixture of 5 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-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-benzoic acid (I-131).
