Procedure
A 1-L reaction vessel was charged with 80.0 g (0.32 mole) of 4-carboxychalcone and 377.7 g (3.17 mole) of thionyl chloride, and heated under reflux for 1 hour. Thereafter, thionyl chloride was removed by distilling, and thus 87.0 g of 4-(chlorocarbonyl)-chalcone was obtained (101% yield). This reaction is shown by the reaction formula in FIG. 1(b).
