実験手順

A mixture of N-n-propyl-3-(3-hydroxyphenyl)piperidine hydrobromide (0.76 g, 0.0025 mol), phenylisocyanate (5.45 g, 0.046 mol), triethylamine (0.5 g, 0.049 mol) and methylene chloride (2 ml) was stirred at r.t. for 18 h. The mixture was partitioned between water and ether. The ether phase was dried and evaporated giving a partly crystalline residue. The residue was dissolved in methanol and chromatographed on a silica gel column (200 g, SiO2) with methanol as eluant. The fractions which according to GLC contained the desired product in pure form were continued and the solvent evaporated. The residue was dissolved in ether and treated with HCl-saturated ether giving a crystalline precipitate. Filtration and washing gave 0.18 g (20%) of the desired hydrochloride, mp. 184°-190° C.
