Procedure

1-(2,4-dichlorobenzyl)-6-(ethoxycarbonyl)benzotriazole (0.60 g) was refluxed under heating in a mixed solvent of 5% aqueous solution of sodium hydroxide (6 g) and ethanol (20 g) for 0.5 hr. After cooling, concentrated hydrochloric acid (4 ml) and water (10 ml) were added to the reaction mixture, and the mixture was extracted with ethyl acetate, concentrated and dried to give the objective compound (0.50 g) as a crude product.
