A solution of 2,6-diethyl-isonicotinic acid tert-butyl ester (635 mg, 2.70 mmol) in 6 N aq. HCl (10 mL) is stirred at 95° C. for 15 h before the solvent is evaporated. The residue is dried under HV to give 2,6-diethyl-isonicotinic acid hydrochloride (523 mg) as a colourless solid, LC-MS: tR=0.42 min, [M+1]+=180.31; 1H NMR (D6-DMSO): δ 7.95 (s, 2H), 3.05 (q, J=7.5 Hz, 4H), 1.31 (t, J=7.5 Hz, 6H).
