Procedure

A solution of 42.0 parts of dimethyl 2-ethyl-3-(3-[2-propylphenoxy]propoxy)phenoxyfumaric acid and 7.36 parts of sodium hydroxide in 50% v/v aqueous methanol was refluxed for four hours. The reaction mixture was cooled, acidified with excess 2N hydrochloric acid and extracted with chloroform. Evaporation of the chloroform and trituration of the residue with 40/60 light petroleum ether gave an oily solid. This solid was dissolved in hot chloroform and addition of 40/60 light petroleum ether to the solution gave 33.8 parts of 2-ethyl-3-(3-[2-propylphenoxy]propoxy)phenoxyfumaric acid, m.pt. 104°-105°.
