Participants

Reaction Steps

To a solution of 10.2 g (31.55 mmol) of 2-bromo-3-(3-hydroxypropyl)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-naphthalene in 80 mL of dimethlformamide was added 9.46 g (138.8 mmol) of imidazole and 10.46 g (69.4 mmol) of tert-butyldimethylsilyl chloride. After 4 hours the reaction mixture was diluted with diethyl ether and washed with 1 N aqueous ammonium chloride and brine. The organic fraction was dried over sodium sulfate and then concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (gradient elution: 1-2% ethyl acetate/hexane) to afford 9.17 g (66%) of 2-bromo-3-(3-t-butyldimethylsiloxypropyl)-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-naphthalene.
