Procedure

37 mgm (0.5 millimols) of calcium hydroxide and 217 mgm (1 millimol) of 4,5-dimethyl-thieno[3,2-d]isothiazole-3-(2H)-one-1,1-dioxide were added to 50 ml of boiling water. The virtually clear resulting solution was filtered and evaporated to 1 ml. 180 mg (76% of theory) of 4,5-dimethyl-thieno[3,2-d]-isothiazole-3(2H)-one-1,1-dioxide calcium salt crystallized out.
