実験手順

Dissolve 2-[4-(4-chloro-butyryl)-phenyl]-2-methyl-propionic acid, methyl ester (2.82 g, 10.0 mmol) and α,α-diphenyl-4-piperidinemethanol (5.58 g, 21.0 mmol) in toluene (20 mL). Reflux for 29 hours, cool in an ice bath, filter, filter the filtrate though silica gel (5 g) and wash the gel with toluene (10 mL). Evaporate the solvent in vacuo and dissolve the residue in ethyl ether (100 mL). Add anhydrous hydrogen chloride and filter to give the title compound as an off-white powder (4.2 g, 76%); mp 165-175° C.
