Procedure

500 mg of 4-Cyano-3-[2-(2,4-dichloro-phenyl)-ethoxy]-benzoic acid methyl ester was dissolved in 50 ml of MeOH:water/3:1. 1 g of lithium hydroxide monohydrate was added to the added to the solution, and the reaction was stirred at RT for 16 h and 2 h at 50° C. The solution was cooled to RT, then acidified with half-concentrated hydrochloric acid. The suspension was concentrated under reduced pressure and then extracted with ethyl acetate. The organic layer was dried over Na2SO4 and the solvent was removed under reduced pressure to yield a white solid.
