Versuchsvorschrift
500 ml of methanol were added to 0.49 gm (12.3 millimols) of calcium, the mixture was refluxed, and 5.0 gm (24.6 millimols) of 5-methyl-thieno[3,2-d]isothiazole-3(2H)-one-1,1-dioxide were added to the suspension thus obtained. The resulting solution was evaporated, and the residue was recrystallized from a little ethanol/ether. 3.9 gm (71% of theory) of 5-methyl-thieno[3,2-d]-isothiazole-3(2H)-one-1,1-dioxide calcium salt were obtained.
