Procedure

2′-(2,4,6-trimethoxybenzylthio)biphenyl-3-ol (0.948 g, 2.48 mmol) was treated with TFA:triethylsilane:DCM (8 ml:3 ml:80 ml). The solution was stirred 30 min. before 40 ml water was added and the mixture was extracted with DCM (2×80 ml). The organic was washed with water, brine, dried over magnesium sulfate and concentrated. The residue was purified by silica flash chromatography (hexane:ethyl acetate 80:20) to afford 0.335 g product (1.66 mmol, 67% yield).
