Participants

Reaction Steps

A solution of 1.4 g (4.9 mmol) of 6-chloro-N-methyl-N-pyridin-2-ylpyridine-3-sulfonamide and 0.96 mL (19.7 mmol) of hydrazine monohydrate in 8 mL of EtOH is heated for 12 hours at 80° C. The precipitate obtained, after cooling to room temperature, is filtered off, washed with 10 mL of EtOH and then dried under vacuum. 0.85 g of 6-hydrazino-N-methyl-N-pyridin-2-ylpyridine-3-sulfonamide is obtained in the form of pale yellow crystals.
