Imidazole → 4-{[tert-Butyl(dimethyl)silyl]oxy}-2,3-dihydro-1H-inden-1-one

Participants

Reaction Steps

To a solution of 4-hydroxy-indan-1-one (1.0 g, 6.75 mmol) in CH2Cl2 (20 mL) was added imidazole (690 mg, 10.12 mmol). The mixture was stirred for 5 minutes, to which was added portionwise tert-butyldimethylsilyl chloride (1.05 g, 5.31 mmol). The mixture was stirred for 3 hours at room temperature and was diluted with EtOAc. The organic layer was washed with 1N HCl, water and brine, dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The crude residue was purified by column chromatography to give 4-(tert-butyl-dimethyl-silanyloxy)-indan-1-one (1600 mg, 90%).
