実験手順

A mixture of 4-[(trifluoromethyl)thio]phenol (4.5 g, 23.2 mmol), Na2WO4.2H2O (0.08 g, 0.24 mmol) and hydrogen peroxide (6 ml, 59 mmol) in acetic acid (25 ml) was heated at 65° C. for overnight. Na2S2O5 (sat.) and NaOH (20%) was added (until pH 8) and the solution was extracted with EtOAc. The combined organic phases were dried (Na2SO4) and evaporated to dryness to give the crude title compound (6.0 g). MS m/z (rel. intensity, 70 eV) 226 (M+, 18), 157 (bp), 109 (14), 93 (52), 65 (53).
