Reaction Steps

5,7-Dimethoxy-2-(pyridin-4-yl)quinazolin-4(3H)-one was synthesized from 2-amino-4,6-dimethoxybenzamide and 4-pyridine carboxaldehyde, using the method described for 5,7-dimethoxy-2-(pyridin-2-yl)quinazolin-4(3H)-one. 5,7-Dimethoxy-2-(pyridin-4-yl)quinazolin-4(3H)-one (142 mg, 63%) was isolated as a pale brown solid and then converted to the corresponding hydrochloride (yellow solid). Selected data: MS (m/z): 284.06; MP 294-295° C. (hydrochloride).
