Paroxetine, a potent and selective inhibitor of 5-hydroxytryptamine (serotonin) uptake, was prepared through a piperidine derivative, which was reported to be one of the paroxetine metabolites in humans. Thus, the piperidine derivative was converted to its N-tert-butoxycarbonyl (N-Boc) derivative, which was then converted to N-Boc paroxetine. Paroxetine hydrochloride propan-2-ol (isopropyl alcohol (IPA)) solvate crystals were directly obtained from the N-Boc paroxetine by adding hydrogen chloride to the N-Boc paroxetine IPA solution. The amount of IPA content in the crystals was reduced by drying with a continuous change of powder X-ray diffraction patterns. Other characterizations of the solvate crystals were also conducted.

A piperidine derivative, which can be used as an intermediate for pharmaceuticals such as paroxetine useful as antidepressants, represented by the general formula (I): STR1 wherein R1 is hydrogen atom, benzyloxycarbonyl group or tert-butoxycarbonyl group; R2 is hydroxymethyl group, an alkylsulfonyloxymethyl group having an alkyl moiety of 1 to 2 carbon atoms, phenylsulfonyloxymethyl group which may have methyl group at the 4-position, (3,4-methylenedioxyphenyl)oxymethyl group, carboxyl group or --CO2 R7 group in which R7 is an alkyl group having 1 to 5 carbon atoms, and Z is methylene group or carbonyl group.
