Reaction Steps
A mixture of 3.2 g of 7-chloro-3-methylthio-2H-1,2,4-benzothiadiazine 1,1-dioxide and 1.1 g of 1-methylpiperazine is heated with stirring in an oil bath at 140° C. for 2 hours. After cooling, the resultant solid is recrystallized from a mixture of dimethylformamide and water to give 3.1 g of the desired product, m.p. above 300° C.
