Procedure

p-Toluoyl chloride (0.48 ml, 3.63 mmol) was added to a solution of 1(S)-[4-(3,4-dichlorobenzyl)piperazin-1-ylmethyl]-2-methylpropylamine (1 g, 3.0 mmol) and triethylamine (0.633 ml, 4.54 mmol) in methylene chloride under nitrogen atmosphere. After 1 h, the product was extracted into ethyl acetate and the organic layer was washed with sodium bicarbonate solution, dried over magnesium sulfate, filtered and concentrated in vacuo. Column chromatography with hexanes/ethyl acetate (1:2) gave N-{1(S)-[4-(3,4-dichlorobenzyl)piperazin-1-ylmethyl]-2-methylpropyl}-4-methylbenzamide (1.2 g) as an oil. The free amine was dissolved in ether and 3.5 equivalents of 1N ethereal HCl solution (10.7 ml) was added. Filtration of the resulting solid provided N-{1(S)-[4-(3,4-dichlorobenzyl)piperazin-1-ylmethyl]-2-methylpropyl}-4-methylbenzamide (1.2 g) as the bis hydrochloride salt, mp 227.8-228.9° C.
