Reaction Steps

A slurry of 40 ml of hexadecyl bromide in 250 ml of tetrahydrofuran containing 3.64 g of magnesium chips is put in a sonic bath. This solution is added dropwise to a stirred solution of 35.3 ml of diethyloxalate in 70 ml of tetrahydrofuran at -15° C. over 1 hour. The reaction mixture is poured into 3N hydrochloric acid and extracted with methylene chloride. The extract is dried and evaporated. The concentrate is purified by chromatography on silica gel using 5% ethyl acetate:petroleum ether. Fractions containing product are combined and evaporated. The residue is crystallized from petroleum ether to give 21.9 g of the desired product as a solid.
