Procedure

A sample (24.1 g) of N,N-dimethyl-1-[1-(4-chlorophenyl)cyclobutyl]-3-methylbutylamine hydrochloride was dissolved in a boiling mixture of water (72 ml) and tetrahydrofuran (7 ml) and the mixture allowed to cool. A solid was collected by filtration and dried at 40° C. to give N,N-dimethyl-1-[1-(4-chlorophenyl)-cyclobutyl]-3-methylbutylamine hydrochloride monohydrate (m.p. 193°-195° C.).
