Procedure
To a solution of 3-formylbenzoic acid (2.0 g, 13.3 mmol) and sodium hydroxide (1.32 g, 33 mmol) in 400 mL of ethanol/water (1:1) is added 2,5-dimethoxyacetophenone (2.4 g, 13.3 mmol) and the resulting solution is stirred overnight at room temperature. The mixture is acidified with concentrated hydrochloric acid and the resulting solid is collected by filtration after diluting the mixture with water (200 mL) to provide 2.9 g of the title compound; mp 152°-155° C.
