Procedure
Z-(R)-1-(2-((2-(2-Methylphenyl)-2-phenylethenyl)oxy)ethyl)-3-piperidinecarboxylic acid ethyl ester (2.0 g, 0.0051 mol, prepared similarly to the method described in Example 50) was dissolved in ethanol (8 ml) and 12 N sodium hydroxide solution (1.3 ml) was introduced. After stirring the solution at room temperature for 2 h, 37% hydrochloric acid (ca. 1.8 ml) was added with cooling, followed by dichloromethane (300 ml) and the mixture was dried (Na2SO4). Filtration and evaporation of the filtrate gave a residue, which was co-evaporated with acetone. The solid product was triturated with ethyl acetate, collected by filtratiion and dried in vacuo to give the title compound (0.70 g, 34%).
