Reaction Steps
To a solution of 1 g (7.25 mmol) of 3-amino-4-pyridinecarboxylic acid in 5 mL of ethyl alcohol was added 2 mL of sulfuric acid. The mixture was warmed under reflux for 2 h. It was cooled and basified with conc. NH4OH solution to pH=8. The resulting solution was extracted with ethyl acetate and the organic layer was washed with brine and water, dried (MgSO4) and concentrated in vacuo to give 1.04 g of the title compound as a white solid (87%).
