Reaction Steps

10.5 ml of n-BuLi as a 1.6M solution in hexane are added dropwise to 4.32 g of 1-bromo-3,5-bis[(tert-butyl)dimethylsilanyloxymethyl]benzene (G. T. Crisp and P. D. Turner, Tetrahedron, 2000, 56 (42), 8335) in solution in 150 ml of THF cooled to −71° C. After 1 h 30, 4.27 ml of acetone are added dropwise. The mixture is allowed to return to AT and then hydrolysed with a saturated aqueous NH4Cl solution. The aqueous phase is extracted with 100 ml of AcOEt, the combined organic phases are dried over MgSO4 and concentrated under RP, and the residue is purified by flash chromatography on silica (Biotage 65+M) using a gradient from 0 to 20% AcOEt in heptane. 2.48 g of 1-(1-hydroxy-1-methylethyl)-3,5-bis[(tert-butyl)dimethylsilanyloxymethyl]benzene are thus obtained.
