実験手順

A mixture of 0.50 gram of N-formyl-α,α-dimethyl-4-(phenylethynyl)-benzylamine, 10.7 ml. of glacial acetic acid, 6.7 ml. of water, and 1.07 ml. of concentrated hydrochloric acid is stirred and refluxed for 2.5 hours. The solution is evaporated to dryness and α,α-dimethyl-4-(phenylethynyl)-benzylamine hydrochloride is obtained as a light tan solid. The product is recrystallized from an isopropyl alcohol-methanol-ether mixture to give pure α,α-dimethyl-4-(phenylethynyl)-benzylamine hydrochloride, m.p. 275°-278° (decomp.).
