Reaction Steps
To a solution of 2-(5-methoxy-1,2,3,4-tetrahydro-1-naphthyl)ethanol (0.20 g) and triphenylphosphine (0.42 g) in dichloromethane (10 ml) was added tetrabromomethane (0.90 g) at 5° C. The solution was stirred at 5° C. for 1.5 hours and evaporated in vacuo. To the residue, ethyl acetate was added and the insoluble material was filtered off. The ethyl acetate solution was evaporated in vacuo. The residue was chromatographed (n-hexane) over silica gel to afford 2-(5-methoxy-1,2,3,4-tetrahydro-1-naphthyl)ethyl bromide (0.18 g) as a colorless oil.
