실험 절차

For the preparation of the starting material of Example 10a, p-(2-bromoethyl)-acetophenone was reacted with sodium azide in dimethylsulfoxide to give p-(2-azidoethyl)acetophenone. Oxidation with sodium hypobromite gave p-(2-azidoethyl)benzoic acid (m.p. 130°-131°, from acetone-hexane), which was converted with thionyl chloride into the corresponding acid chloride and subsequently with ammonia into p-(2-azidoethyl)benzamide. Treatment with triphenylphosphine and hydrolysis gave p-(2-aminoethyl)benzamide, m.p. 132°-133° (from ethanol).
