Procedure

In 50 ml of ethyl ether were dissolved 3.96 g of 6-acetoxy-2-isopropyl-2H-pyran-3(6H)-one and 4.84 g of cetyl alcohol with stirring. Into the solution was gradually added 0.1 ml of anhydrous stannic chloride at a temperature of 5° to 10° C. The reaction mixture was stirred at room temperature for 7 hours, washed twice with aqueous sodium hydrogencarbonate solution and once with saturated aqueous sodium chloride solution and then dried over anhydrous magnesium sulfate. By the distillation of solvent was obtained 7.0 g of 6-cetyloxy-2-isopropyl-2H-pyran-3(6H)-one [compound 1] in a yellow viscous oily form.
