Notes: The methyl derivative of tolbutamide, obtained by the action of dimethyl sulfate, has been subjected to g.c.-m.s. at high resolution. From the mass spectrum it is deduced that methylation of the sulfonamide nitrogen atom has occurred. During the loss of SO2 from the molecular ion, aryl rearrangement to both oxygen and nitrogen occurs in the ratio of 1:2.
