실험 절차

To a suspension of 2.24 g of tert-butyl {(1R,2S)-2-[(2-{[(2-methoxyethyl)amino]carbonyl}-6-methylquinazolin-4-yl)amino]cyclohexyl}carbamate in 10 ml of ethyl acetate, 10 ml of a 4 N hydrogen chloride-ethyl acetate solution was added, and the mixture was stirred at room temperature for 48 hours. To the reaction solution, 20 ml of diethyl ether was added, and the mixture was stirred for 30 minutes. Then, the deposited substance was collected by filtration, washed with diethyl ether and dried under reduced pressure. The resulting powder was purified by Fuji Silysia NH silica gel column chromatography (chloroform:methanol=20:1), whereby 1.61 g of a desired compound was obtained as a colorless powder.
