Versuchsvorschrift

A mixture of 0.30 g (0.91 mmole) 2-chloro-9-cyclopentyl-5-ethyl-7,7-difluoro-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-138) and 0.18 g (1.09 mmole) 4-amino-3-methoxy-benzoic acid in a 1:4 mixture of 5 mL of ethanol and 1 M 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 0.28 g of 4-(9-cyclopentyl-5-ethyl-7,7-difluoro-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methoxy-benzoic acid (I-156).
