Procedure

A mixture of 0.135 g (0.00048 mole) of 2-chloro-9-cyclopentyl-5-methyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-10), 0.096 g (0.00058 mole) of 4-amino-3-methoxy-benzoic acid, 1 mL of ethanol, 3 mL of water, and 2 drops of hydrochloric acid was heated at 100 degrees overnight. Upon cooling, a precipitate formed which was collected by filtration to give 0.14 g of 4-(9-cyclopentyl-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-yl amino)-3-methoxy-benzoic acid (I-10) as an off-white solid.
