Procedure

A mixture of 0.0449 g (0.000146 mole) of 2-chloro-9-cyclopentyl-8,9-dihydro-5-methylspiro[5H-pyrimido[4,5-b][1,4]diazepine-7,1′-cyclopropan]-6(7H)-one (VII-53), 0.0222 g (0.00016 mole) of 4-amino-benzoic acid, 0.8 mL of ethanol, 3.2 mL of water and 3 drops of hydrochloric acid was heated at reflux for 17 hours. The mixture was cooled, and the precipitate which formed was collected by filtration to give 0.029 g of 4-[(9-cyclopentyl-6,7,8,9-tetrahydro-5-methyl-6-oxospiro[5H-pyrimido[4,5-b][1,4]diazepine-7,1′-cyclopropan]-2-yl)amino]-benzoic acid (I-62a) as a white solid.
