참여 물질

반응 단계

10% sodium hydroxide aqueous (40 ml) was added under stirring to a solution of 3-methoxy-4-ethoxybenzaldehyde (9.09 g, 50 mmol) in acetone (25 ml), 95% ethanol (25 ml) and water (200 ml). The reaction mixture was stirred for 24 hr at room temperature, after the reaction completed, the reaction mixture was neutralized with 6N hydrochloric acid to adjust pH=7.0. The precipitated solid was collected by filtrating and washed with water and ethanol successively, dried, and then recrystallized from 95% ethanol to give 7.38 g of a pale yellow solid, mp: 95-97° C., yield: 66.5%.
