実験手順

3.26 g (27.44 mmoles) of thionyl chloride was added, at room temperature, to a solution of 1.50 g (9.15 mmoles) of (5-chloro-3-methyl-isothiazol-4-yl)-methanol dissolved in 10 ml of chloroform. The mixture was stirred for 3 hours to give rise to a reaction. After confirmation of the completion of the reaction, the reaction mixture was subjected to vacuum distillation to remove the solvent contained therein, to obtain 1.67 g (yield: quantitative) of 4-chloromethyl-5-chloro-3-methylisothiazole.
