Reaction Steps

404 μl of thioacetic acid and 376 mg of zinc iodide are added to 1 g of 1-(1-hydroxy-1-methylethyl)-3,5-bis[(tert-butyl)dimethylsilanyloxymethyl]benzene in solution in 4.7 ml of 1,2-dichloroethane. The mixture is heated at 50° C. for 40 min. After returning to AT, the salts are removed by filtration, the organic phase is concentrated under RP and the residue is purified by flash chromatography on silica (Biotage 40+M) using a gradient from 0 to 30% AcOEt in heptane. 248 mg of 1-[3-[(tert-butyl)dimethylsilanyloxymethyl]-5-(hydroxymethyl)phenyl]-1-methylethyl thioacetate are thus obtained.
