Reaction Steps

Under nitrogen dissolve 1-benzhydrylazetan-3-ol (5 g, 20.9 mmol), imidazole (3.5 g, 52.25 mmol) in anhydrous DMF (25 mL). Cool solution in an ice bath, add slowly tert-butyldimethylsilyl chloride (50 wt. % solution in toluene, 6.3 g, 41.8 mmol). Stir at RT for 22 h. Dilute with EtOAc and wash with saturated aqueous sodium bicarbonate solution. Separate organic layer, dry (sodium sulfate), concentrate and purify (silica gel chromatography, eluting with 10:90 EtOAc:hexanes) to give the title compound (3.89 g, 53%).
