Regioselective Synthesis of Novel N2- and N4-Substituted 7-Methylpyrazolo[4,5-e][1,2,4]thiadiazines

Regioselective Synthesis of Novel N2- and N4-Substituted 7-Methylpyrazolo[4,5-e][1,2,4]thiadiazines

The new compound 7-methylpyrazolo[4,5-e][1,2,4]thiadiazin-3(2H,4H)-one1,1-dioxide (5) was synthesized and its novel mono N2- or N4-substituted derivatives 6and 7 were prepared by regioselective N-alkylation of 5 with different molar ratios ofNaH and alkyl halides. Based on the regioselective alkylat...
