Procedure

To a solution of 0.758 g (2,5-dimethylphenyl)(2-(methylthio)phenyl)methanone and 1 ml triethylsilane was added 5 ml TFA. The reaction mixture was stirred at RT for 1 hour before water was added. The reaction mixture was extracted with ethyl acetate (2×70 ml) and the combined organic extracts were washed with brine, dried over magnesium sulfate, filtered and concentrated. Flash silica chromatography (hexane:ethyl acetate 80:20) yielded 0.666 g product.
