To a solution of 4-aminoanisole (50 g, 0.406 mol) in EtOH (500 mL) was added diethyl ethoxymethylenemalonate (81 mL, 0.406 mol). The reaction solution was refluxed for 4 h; LCMS showed complete reaction. The reaction solution was concentrated under reduced pressure to give the desired product (118 g, 100%) as a crystalline solid.
