Boron tribromide was added dropwise, under argon to an about -78° C. solution of about 12.16 g of 4-methoxy-1-tetradecyl-benzene in about 125 ml of methylene chloride. The reaction was stirred for about 21/2 hours at about -78° C., then water was added dropwise, the organic layer separated, washed with sodium bicarbonate solution and evaporated, giving about 11.8 g of the desired title compound, mp 70°-71° C.
