Participants

Reaction Steps

A solution of 2.7 g of 4-[2-(trans-4-pentylcyclohexyl)ethyl]phenol in absolute dichloromethane was treated dropwise at 0° C. with a solution of 1.6 g of bromine in 20 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 3.4 g of 2-bromo-4-[2-(trans-4-pentylcyclohexyl)ethyl]phenol.
