Reaction Conditions

Reaction Steps

To a -78° C. solution of 17.4 g (0.10 mole) of dibromomethane and 21.7 g (0.050 mole) of 3-[2-benzyloxy-4-(1,1-dimethylheptyl)phenyl]-4,5-dimethylcyclohexanone in 100 ml of tetrahydrofuran is added dropwise over a period of 2 hours a solution of lithium dicyclohexylamide (0.10 mole) in 100 ml of tetrahydrofuran. The reaction is stirred one hour longer at -78° C. and quenched by addition of 2 ml (0.11 mole) of water. The reaction is added to 300 ml ether and 200 ml water. The ether extract is dried over magnesium sulfate and evaporated. The crude product is purified via column chromatography on 500 g of silica gel eluted with ether-pentane to give pure 3-[2-benzyloxy-4-(1,1-dimethylheptyl)phenyl]-1-dibromomethyl-4,5-dimethylcyclohexanol.
