Versuchsvorschrift

A mixture of 0.0398 g (0.00013 mole) of 2-chloro-9-cyclopentyl-5,7,7-trimethyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-38), 0.022 g (0.000143 mole) of 4-amino-3-methylbenzoic acid, 0.7 mL of ethanol, 2.8 mL of water and 3 drops of hydrochloric acid was heated at reflux for 17 hours. The mixture was cooled, and the white precipitate that formed was collected by filtration to give 0.0229 g of 4-(9-cyclopentyl-5,7,7-trimethyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-methyl-benzoic acid (I-56a) as a white solid.
