Procedure

A mixture of 0.059 g (0.0002 mole) of (rac)-2-chloro-9-cyclopentyl-5,8-dimethyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-3), 0.033 g (0.0002 mole) of 4-amino-3-methoxy-benzoic acid, 0.5 mL of ethanol, 2 mL of water, and 2 drops of hydrochloric acid was heated to 100 degrees overnight. Upon cooling, a precipitate formed which was collected by filtration to give 0.062 g of (rac)-4-(9-cyclopentyl-5,8-dimethyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-yl amino)-3-methoxy-benzoic acid (I-3) as an off-white solid.
