Procedure

5,7-Dimethoxy-2-(4-methoxyphenyl)quinazolin-4(3H)-one was synthesized from 2-amino-4,6-dimethoxybenzamide and 4-methoxy benzaldehyde, using the method described for 5,7-dimethoxy-2-(pyridin-2-yl)quinazolin-4(3H)-one. 5,7-Dimethoxy-2-(4-methoxyphenyl)quinazolin-4(3H)-one (106 mg, 44%) was isolated as an off-white solid. Selected data: MS (m/z): 312.99; MP 276-277° C.
