Procedure

A mixture of 3-benzyloxy-5-fluoro-2-nitroanisole(0.75 g), dimethylsulphoxide(5 mL) and 5N aqueous sodium hydroxide(2 mL) was stirred at 70° C. for 3 h. The mixture was diluted with water and acidified with concentrated hydrochloric acid, extracted with ethyl acetate and the extract was washed with water dried and evaporated to dryness to give the product (0.71 g), (m/e274, MH−).
