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 2N 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°.
