実験手順

A 2-phenylbenzotriazole-N-oxide which is the chosen starting material is dissolved in a solvent contained in a reaction vessel into which a hydrogenation catalyst and a basic substance are then placed. After the air in the reaction vessel has been replaced by hydrogen, a given amount of hydrogen is charged into the reaction vessel, and the reaction is then allowed to proceed under atmospheric pressure or a given pressure at a temperature of room temperature to 170° C. under agitation. After the reaction has been completed, the catalyst is filtered off, the solvent layer is washed with water, and the solvent is distilled off. The crude product is then purified by recrystallization to obtain the corresponding 2-phenylbenzotriazole as a pure product.
