Reaction Steps

EtOH (500 mL) was added to 2-amino-nicotinic acid (25 g), followed by H2SO4 (25 mL, conc), and the mixture stirred at 75° C. overnight. The reaction mixture was then redissolved in H2O, neutralized with Na2CO3 (aq), and the resulting precipitate filtered and dried to provide 2-amino-nicotinic acid ethyl ester, which was used without further purification.
