Reaction Conditions:

with ammonium hydroxide at 130; for 12 h;Sealed tube;

Steps:

68 2-Amino-6-chloropyridine-3-carboxylic acid
A solution of 2,6-dichloropyridine-3-carboxylic acid (3 g, 0.0157 mol) in aqueous ammonia (30 mL) was heated in a sealed tube at 130°C for 12 h. The reaction mixture was concentrated and the resulting crude solid was triturated with diethyl ether to afford the title compound (2.5 g, 93%). δ_Η (400 MHz, DMSO-de) 8.02 (d, J 8.0 Hz, IH), 7.55 (s, 2H), 6.62 (d, J 8.0 Hz, IH). LCMS: mlz 173 (97.70%)
