Diethyl acetamidomalonate (6.996 g) and 3.189 g of sodium ethoxide were dissolved in 130 ml of dry ethanol and a solution of 10.698 g of 1-bromo-12-tetrahydropyranyloxydodecane in 200 ml of dry ethanol was added thereto. The mixture was refluxed under heating for 8 hours. The solvent was distilled away under reduced pressure and the residue was purified by silica gel column chromatography to give 5.837 g of diethyl 2-acetamido-2-(12-tetrahydropyranyloxydodecyl)malonate.
