Reaction Steps

2-Methoxy-isonicotinic acid methyl ester (23.0 g, 137 mmol) and hydrazine hydrate (8.95 g, 178 mmol) were dissolved in ethanol and stirred at 75° C. for 12 hours. The reaction mixture was concentrated and the remaining solid was tritiated in hexanes/ether (80:20), filtered and dried to afford the title compound as a solid (18.4 g, 80%).
