Procedure

To a stirred solution of Ethyl 3-(2,6-dimethylbenzyloxy)phenylacetate (Step B, 4 g, 13.6 mmol) in absolute ethanol (30 ml) was added 1N NaOH (20 ml) at room temperature. The reaction mixture was stirred for 3 hours, acidified by 1N HCl, and concentrated. The residue was taken into chloroform and washed with 0.1N HCl, dried over Na2SO4, filtered, concentrated and purified by flash chromatography on a silica gel column (hex:ethyl acetate 1:1) to give the title compound.
