Reaction Steps

In 12 ml of benzene were dissolved 341 mg (1.46 mmol) of 2-[(4-chlorobenzyl)thio]-1,3-propanediol and 375 mg (1.75 mmol) of (E)-4-(trifluoromethyl)-a-methylcinnamaldehyde, and 3 mg of p-toluenesulfonic acid were added to the solution, followed by heating of the resulting mixture with reflux under nitrogen atmosphere for 2 hours. After cooling, the reaction mixture was washed with an aqueous sodium hydrogencarbonate solution. The residue obtained by evaporation of the solvent was subjected to column chromatography using 15 g of silica gel. The fractions eluted with a mixed solvent of hexane-ethyl acetate (9:1) were collected and the thus obtained solid was washed with hexane to obtain 370 mg (yield: 59%) of the title compound having a melting point of 93 to 95° C.
