(2-Bromoethoxy)(tert-butyl)dimethylsilane (1.48 mL) was added dropwise to a suspension of 3-mercaptobenzoic acid (1.07 g) and potassium carbonate (1.91 g) in DMF (15 mL). The resulting suspension was stirred for 2 h. The reaction was carefully acidified by dropwise addition of aqueous HCl solution (2M, 10 mL) and poured into water (100 mL). The resulting aqueous was extracted with ethyl acetate (3×100 mL). The combined organics were washed with brine (50 mL), dried over sodium sulphate, filtered and evaporated to give the subtitled compound as a clear oil. Yield 2.8 g.
