Versuchsvorschrift

A solution of 0.1 g of (5-(1-hydroxy-1-methyl-ethyl))-pyridine-2-sulfonic acid amide, product of example 14 b), in CF3CO2H (2 ml) was refluxed for 20 h. The solvent was then removed in vacuo to give 5-isopropenyl-pyridine-2-sulfonic acid amide as a white solid which was essentially pure. EI mass spectrum, m/e 198 (M calculated for C8H10N2O2S: 198).
