Procedure

A solution of 4-(3-benzyloxy-4-methoxyphenoxy)-3,5-dimethylnitrobenzene (1.65 g), TFA (3.5 mL) and thioanisole (2.2 mL) were stirred for 4 h. The reaction was partitioned between ethyl acetate and water, the organic layer dried over sodium sulfate and concentrated in vacuo. Flash chromatography afforded 4-(3-hydroxy-4-methoxyphenoxy)-3,5-dimethylnitrobenzene (1.2 g) as a yellow oil.
