Reaction Conditions

Reaction Steps

2,2,5,5-Tetramethyl-1-cyclopentylmethanol is dissolved in benzene and stirred at 0° C. under argon. A solution of phosphorus tribromide in benzene is added and the mixture is stirred for 2 hours and then heated to 60° C. for 4 hours. The mixture is cooled, poured into ice and extracted with ether. The organic layer is washed with saturated NaHCO3, dried over MgSO4 and evaporated to yield 2,2,5,5-Tetramethyl-1-cyclopentylmethyl bromide.
