Reaction Steps

To a solution of 2-methoxymethoxybenzaldehyde (15.0 g, 90.3 mmol) in pyridine (80 mL) were added malonic acid (18.8 g, 181 mmol) and piperidine (1.0 mL, 9.0 mmol) followed by heating to reflux for 6 hours. Water was added to the residue prepared by evaporation of the solvent therefrom in vacuo and the mixture was acidified with a diluted hydrochloric acid. The crystals separated out therefrom were filtered and washed with water to give the title compound (16.5 g, 88%).
