Procedure

A suspension of 2-(3,5-dichloro-2-((hydroxyimino)methyl)phenoxy)ethyl acetate (1.15 mmol) in 2 mL AcOH was cooled to 0° C. and zinc dust (4.36 mmol) was added. The reaction mixture was stirred at RT for 1 h. It was filtered over a pad of celite and washed with EtOAc and MeOH. The filtrate was conc. and redissolved in water (pH 4 with 2N HCl solution). It was washed once with EtOAc, the ageous phase was basified with 1M NaOH solution, extracted 3 times with EtOAc and DCM. The comb. org. layers were dried over MgSO4 and concentrated in vacuo to give the desired product as white solid.
