反応手順
The above-mentioned dodecanediol monotetrahydropyranyl ether (7.882 g) and 11.437 g of carbon tetrabromide were dissolved in 78 ml of dichloromethane. Triphenylphosphine (10.843 g) was added thereto under ice-cooling and the mixture was stirred at 0° C. for 5 minutes. The solvent was distilled away under reduced pressure and the residue was purified by silica gel column chromatography to give 4.029 g of 1-bromo-12-tetrahydropyranyloxydodecane.
