Procedure
A solution of 2-diethylamino-6-methyl-isonicotinic acid ethyl ester (6.39 g, 27.0 mmol) in 6 N aq. HCl (100 mL) is stirred at 80° C. for 72 h before the solvent is removed in vacuo. The remaining solid is dried under HV to give 2-diethylamino-6-methyl-isonicotinic acid hydrochloride (6.96 g) as a yellow solid; LC-MS: tR=0.53 min; [M+H]+=209.09; 1H NMR (D6-DMSO): δ 1.17 (t, J=6.8 Hz, 6H), 2.51 (s, 3H), 3.68 (q, J=6.3 Hz, 4H), 6.96 (s, 1H), 7.15 (s br, 1H).
