The 2,5-bis-methanesulfonyl-pyridine and anhydrous hydrazine are stirred in ethanol for two hours between room temperature and reflux temperature. After cooling to room temperature the mixture is concentrated. The residual solid is washed with aqueous saturated NaHCO3 and water and collected by filtration to give a pale yellow solid. The solid is treated with 10% methanolic HCl and the precipitate is collected by filtration to give the title compound.
