Reaction Steps

A solution of acetic acid 4-benzyloxy-3-methanesulfonylaminophenyl ester (1.6 g) and potassium hydride (2.67 g) in methanol (10 ml) was stirred for 18 hours at room temperature. The reaction mixture was acidified with 1N hydrochloric acid to pH 5-7 and extracted with ethyl acetate. The extract was washed with brine, dried over magnesium sulfate, and evaporated in vacuo. The residue was chromatographed (hexane-ethyl acetate) over silica gel to afford N-(2-benzyloxy-5-hydroxyphenyl)methanesulfonamide (750 mg).
