Versuchsvorschrift

A mixture of 0.5 g (0.0017 mole) of 2-chloro-7,7-difluoro-9-isopropyl-5-methyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-292b) and 0.35 g (0.002 mole) of 4-amino-3-methoxy-benzoic acid in 20 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 0.5M hydrochloric acid and water and dried to give 0.40 g of 4-(7,7-difluoro-9-isopropyl-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-benzoic acid (I-292).
