3-Isopropylamino-4-methyl-4H-pyrido[4,3-e][1,2,4]thiadiazine 1,1-Dioxide

The title compound, C₁₀H₁₄N₄O₂S, is the 4-methyl analogue of an original potassium channel opener molecule related to diazoxide. The crystal structure determination of a compound with a methyl substituent in the 4-position provides geometric reference data. These may serve for analysing the preferential 2H- or 4H-tautomeric form adopted in unsubstituted derivatives of this class of compounds in the solid state.
