Reaction Steps

To a solution of 1-aminopyridinium iodide (139 g, 626 mmol) in acetonitrile (1.25 L) was added 10% aqueous sodium hydroxide solution (751 mL, 1.88 mmol), and the mixture was stirred at room temperature for 12 hr. Half of the reaction mixture was evaporated under reduced pressure, and the residue was extracted with dichloromethane. The extract was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure to give the title compound (47.0 g, yield 56%)
