実験手順
5.0 g (0.03 mol) of 1-hydroxymethyl-5-methylbenzotriazole and 2.9 g (0.03 mol) of aniline were suspended in ethanol and refluxed for 1 hour. The insoluble substance was removed by filtration while it was still hot and the filtrate was cooled to obtain crude crystals. By recrystallization of the crude crystals from ethanol 4.2 g of the desired compound having a melting point of 149° to 152° C. was obtained.
