실험 절차

36.5 g (0.2 mol) of 2,3,5,6-tetramethylbenzyl chloride, 46.0 g (0.4 mol) of 2-aminoheptane and 100 ml of benzene are refluxed for 2 hours. The solvent is then removed in vacuo. A solution of 8 g (0.2 mol) of sodium hydroxide in methanol is then added to the residue to liberate the free base. The reaction product is separated from the precipitated sodium chloride by means of a suction filter, and the excess of 2-aminoheptane is removed by vacuum distillation. The 2-(2,3,5,6-tetramethylbenzyl)aminoheptane obtained is then treated with ethereal hydrochloric acid to convert it into the hydrochloride which is recrystallised from methanol/ethyl acetate. The melting point of the hydrochloride is 155° C.
