실험 절차

A mixture of 1.1 g (3.481 mmole) of 2-chloro-9-cyclopentyl-7,7-difluoro-5-methyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one (VII-20), 0.746 g (4.525 mmole) of 4-amino-3-ethylbenzoic acid, 10 mL of ethanol and 40 mL of 1M hydrochloric acid was heated at reflux for 18 hours. The mixture was cooled and the white precipitate was collected by filtratration, washed with cold water and dried in vacuum to give 0.3421 g of 4-(9-cyclopentyl-7,7-difluoro-5-methyl-6-oxo-6,7,8,9-tetrahydro-5H-pyrimido[4,5-b][1,4]diazepin-2-ylamino)-3-ethyl-benzoic acid (I-194) as off-white solid.
