Procedure
1-(2-((2,2-bis(2-Ethylphenyl)ethenyl)oxy)ethyl)-1,2,5,6-tetrahydro-3-pyridinecarboxylic acid methyl ester (1.40 g, 0.00323 mol, prepared similarly to the method described in Example 70) was dissolved in ethanol (10 ml) and 12 N sodium hydroxide solution (0.8 ml) was introduced. After stirring the solution at room temperature for 5 h, 37% hydrochloric acid solution was added until the pH was measured as ca. 1. Dichloromethane (250 ml) was introduced, and the mixture was dried (Na2SO4), filtered and evaporated to a residue, which was co-evaporated with acetone. Recrystallization from acetone provided the title compound (0.80 g, 57%) as a white solid.
