Imidazole → (3-((Tert-butyldimethylsilyloxy)methyl)phenyl)methanol

Participants

Reaction Steps

33.3 g of tert-butyldimethylsilyl chloride is added to a solution of 30 g of 3-hydroxymethylbenzyl alcohol and 30 g of imidazole in 250 ml of dimethylformamide at 0° C. under argon and stirred for. 20 hours at 25° C. It is diluted with 1.5 1 of ether, shaken twice with 100 ml of 10% sulfuric acid each, washed neutral with brine, dried on sodium sulfate and concentrated by evaporation in a vacuum. The residue is chromatographed on silica gel. With hexane/0-80% ether, 23.4 g of 3-tert-butyldimethylsilyloxymethyl-benzyl alcohol is obtained as colorless oil.
