실험 절차
A solution of 5.5 g of 1-methoxy-2-(2-methylsulphanyl-vinyl)-benzene in 15 ml of dimethylformamide is heated to 80° C. with 4.7 g of POCl3 for 2 hours with stirring. After cooling diethylether and water are carefully added and the mixture obtained is adjusted to pH 9 with aqueous NaOH solution (10%). The organic phase is separated off and after drying the solvent is eliminated in vacuo. Chromatography on silica gel (cyclohexane:ethyl acetate 70:30) yields 2.5 g of 2-(2-methoxyphenyl)-3-methylsulphanyl-propenal.
