Reaction Steps

A solution of 3-(4-hydroxyphenyl)-1-propanol (10.0 g, 66.0 mmol) and imidazole (6.7 g, 98.4 mmol) in N,N-dimethylformamide (50 ml) was cooled to 0-5° C. and treated dropwise with tert-butylchlorodiphenylsilane (21.5 g, 78.2 mmol). The resulting mixture was stirred at 0-5° C. for 2 h and then quenched by addition of water (400 ml) and toluene (500 ml). The organic phase was washed with water, brine and dried over anhydrous magnesium sulfate. Evaporation of the solvent and chromatography of the residue or silica gel (elution toluene-ethyl acetate, 95:5) gave 24.8 g (96%) of the title material as a clear oil.
