Reaction Steps

3-Chloro-5-difluoromethoxyphenylacetic acid methyl ester (1 g, 4 mmol; see step (vi) above) and methyl formate (1 g, 16 mmol) were dissolved in ether (100 mL) and cooled in an ice-bath (ca. 2° C.). Then, finely cut sodium (180 mg, 7.8 mmol) and methanol (1 mL) were added and the mixture was left in the ice-bath with stirring overnight. Water (100 mL) was added carefully and the phases were separated. The water containing phase was acidified with hydrochloric acid (2 M) to pH 1 and extracted with ether (2×100 mL). The extract was dried over sodium sulphate, filtered and concentrated at reduced pressure. The residue was chromatographed on silica (hexane:ethyl acetate (1:1)) which gave 400 mg, 1.4 mmol (yield: 36%) of the sub-title compound.
