実験手順
A mixture of 0.45 gram of α,α-dimethyl-4-(phenylethynyl) -benzylamine hydrochloride, 61 ml. of absolute methanol, and 163 mg. of platinum dioxide catalyst is hydrogenated at 40 p.s.i. for one hour. The hydrogenation is stopped, the catalyst is removed by filtration, and the methanol is removed by evaporation. The residue is partitioned between benzene and 10% sodium hydroxide solution. The benzene phase is washed well with water, dried over magnesium sulfate, filtered, and the benzene is evaporated. The residual oil is dissolved in ether and treated with ethanolic hydrogen chloride. The precipitate is collected and recrystallized from isopropanol and ether to give α,α-dimethyl-4-phenethylbenzylamine hydrochloride, m.p. 225°-228° C.
