反応手順
2-(4-(5,7-Dimethoxy-4-oxo-3,4-dihydroquinazolin-2-yl)phenoxy)acetic acid was synthesized from 2-amino-4,6-dimethoxy-benzamide and (4-formyl phenoxy)acetic acid, using the method described for 2-(4-hydroxyphenyl)-5,7-dimethoxyquinazolin-4(3H)-one. 2-(4-(5,7-Dimethoxy-4-oxo-3,4-dihydroquinazolin-2-yl)phenoxy)acetic acid (135 mg, 21%) was isolated as an off-white solid. Selected data: MS (m/z): 357.04; MP 287-290° C.
