[(6,7-Dichloro-2-ethylidene-1-oxo-2,3-dihydro-1H-inden-5-yl)oxy]acetic acid (U.S. Pat. No. 3,704,314) (30.1 gm., 0.1 mole) is dissolved in methanol (150 ml.) and conc. sulfuric acid (0.5 ml.) added. The mixture is stirred and refluxed for 2 hours. The solvent is removed in vacuo by evaporation on a rotary evaporator and the residue dissolved in ethyl ether, washed with water and dried over sodium sulfate. The ether is removed by evaporation in vacuo in a rotary evaporator to give methyl [(6,7-dichloro-2-ethylidene-1-oxo-2,3-dihydro-1H-inden-5-yl)oxy]acetate.
