Reaction Steps

(R)-N-(2-(3-(2-Methylphenyl)-3-phenyl-2-propen-1-yloxy)ethyl)-3-piperidinecarboxylic acid ethyl ester (2.3 g, 5.6 mmol) was dissolved in ethanol (10 ml) and a 12 N sodium hydroxide solution (1.4 ml) was added. The reaction mixture was stirred at room temperature for 4 h. A concentrated hydrochloric acid solution was added with cooling of the reaction vessel in an ice-bath until pH 1 and dichloromethane (250 ml) was added. The resulting emulsion was dried (Na2SO4) and the solvent was evaporated in vacuo to give a residue which was crystallised from acetone. This afforded 1.75 g (76%) of the title compound.
