Vorschrift

Tributyltin hydride is added dropwise to a solution of 12-bromo-1-dodecanol and excess bis(1-oxyl-2,2,6,6-tetramethylpiperidin-4-yl) sebacate in chlorobenzene. The mixture is heated to facilitate reaction. The crude reaction mixture is passed through silica gel with heptane and then heptane/ethyl acetate to afford the title compound.
