실험 절차

A mixture of 40.64 g (0.119 mole) of (rac)-3-[(2-chloro-5-nitro-pyrimidin-4-yl)-cyclopentyl-amino]-2-methyl-propanoic acid methyl ester (IV-1) in 1500 mL of ethyl acetate and 14 g of 5% palladium on carbon catalyst was stirred under an atmosphere of hydrogen until hydrogen uptake was complete. The mixture was filtered through a pad of Celite, washing the filter pad with dichloromethane. Concentration under reduced pressure gave 35.2 g of (rac)-3-[(5-amino-2-chloro-pyrimidin-4-yl)-cyclopentyl-amino]-2-methyl-propanoic acid methyl ester (V-1), which also contained a small amount of (rac-)-2-chloro-9-cyclopentyl-7-methyl-5,7,8,9-tetrahydro-pyrimido[4,5-b][1,4]diazepin-6-one. This material was used directly in the next step without further purification.
