Procedure

A mixture of 0.50 g (0.0014 mole) of 2-chloro-7,7-difluoro-5-methyl-9-(3-phenyl-propyl)-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-281) and 0.27 g (0.0017 mole) of 4-amino-3-methoxy-benzoic acid in 3.2 mL of ethanol-water-hydrochloric acid (20:80:1) was refluxed for 18 hours, then cooled and partially concentrated under reduced pressure. The resulting solid was collected by filtration, washed with water and dried to give 0.53 g of 4-[7,7-difluoro-5-methyl-6-oxo-9-(3-phenyl-propyl)-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino]-3-methoxy-benzoic acid (I-281).
