PROCEDURE

实验过程

74.8 g (0.63 mol) of thionyl chloride in 50 ml of dry toluene were added dropwise at 50° C. to a solution of 139.0 g of 2-chloro-3-(4,5-dihydroisoxazol-3-yl)-4-methylsulfonylbenzoic acid, 1 ml of dimethylformamide and 1 l of dry toluene. After the mixture had been heated for 6 hours at 110° C., the solvent was distilled off. This gave 2-chloro-3-(4,5-dihydroisoxazol-3-yl)-4-methylsulfonylbenzoyl chloride in quantitative yield.
