To a solution of 1,3-phenylenedimethanol (10.00 g, 72.38 mmol, Aldrich) in DCM (200 mL) was added 1H-imidazole (5.17 g, 76.0 mmol, Aldrich), followed by the addition of tert-butylchlorodiphenylsilane (19.8 mL, 76.0 mmol, Aldrich) and 4-dimethylaminopyridine (0.88 g, 7.2 mmol, Aldrich). After stirring overnight, the reaction was partitioned between DCM and water, the organic layer was dried over sodium sulfate, filtered and concentrated. The product was purified by flash chromatography (gradient elution, 0 to 20% EtOAc/hexanes). Yield: (7.9 g, 29%).
