Participants

Reaction Steps

To a solution of 1-amino-3-(hydroxymethyl)pyridinium 2,4-dinitrobenzenolate (100 g, 323 mmol) in acetonitrile (1.08 L), was added 2 N sodium hydroxide (485 mL) at room temperature, and the mixture was stirred for 12 hr. Acetonitrile was evaporated under reduced pressure, and the residual aqueous solution was extracted with 3 times with chloroform. The extract was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure. The residue was purified by recrystallization (ethyl acetate/hexane) to give the title compound (14.0 g, yield 29%).
