PROCEDURE

实验过程

A solution of 6-methoxy-3-((pivaloyloxy)methyl)-7-((1-tert-butyloxycarbonylpiperidin-4-yl)methoxy)-3,4-dihydroquinazolin-4-one (7.9 g, 16 mmol) in methylene chloride (80 ml) containing 5.5M hydrogen chloride in isopropanol (80 ml) was stirred for 1 hour at ambient temperature. Ether was added and the solid was collected by filtration, washed with ether and dried under vacuum at 60° C. to give 6-methoxy-7-((piperidin-4-yl)methoxy)-3-((pivaloyloxy)methyl)-3,4-dihydroquinazolin-4-one hydrochloride (6.9 g, 100%).
