Procedure

1-(2-((2-(3-Chlorophenyl)-2-(2-methylphenyl)ethenyl)oxy)ethyl)-1,2,5,6-tetrahydro-3-pyridinecarboxylic methyl ester (0.60 g, 0.0014 mol, prepared similarly to the method described in Example 70) was dissolved in ethanol (5 ml) and 12 N sodium hydroxide solution (0.35 ml) was introduced. After stirring the solution at room temperature for 3 h, 37% hydro chloric acid solution was added, until the pH 1. Dichloromethane (200 ml) was introduced, and the mixture was dried (Na2SO4), filtered and evaporated to a residue, which was co-evaporated twice with acetone. The residue was recrystallized from acetone/ethyl acetate to give the title compound (0.33 g, 55%) as white crystals.
