Versuchsvorschrift

To the solution of 4-chlorobenzaldehyde (8.43 g, 60 mmol) in acetone(60 ml) and ethanol (6 ml) was added under stirring 10% NaOH aqueous solution(48 ml) and water(240 ml), the reaction solution was stirred at 25° C. for 8 hr. The precipitated solid was collected by filtration and washed with water, dried to give the title compound 10.5 g as a white solid, mp 56-57° C., yield: 96.9%.
