Boron tribromide → HCID 178444415, compound

Participants

Reaction Steps

A solution of 2.6 g of boron tribromide in 50 ml of absolute dichloromethane was treated dropwise at 0° C. with a solution of 2.0 g of 2-(trans-4-pentylcyclohexyl)-1-(4-methoxyphenyl)ethane in 50 ml of absolute dichloromethane. The mixture was stirred for 1 hour and then poured into ice-water. The organic phase was separated and the aqueous phase was back-extracted three times with 50 ml of dichloromethane each time. The combined organic phases were washed with 50 ml of 2 N sodium carbonate solution and several times with water, dried over magnesium sulphate and concentrated. Recrystallization of the resulting crude product from hexane at 0° C. gave 1.8 g of 4-[2-(trans-4-pentylcyclohexyl)ethyl]phenol of m.p. 102° C.
