실험 절차

A solution of 2,6-dimethylisonicotinic acid tert.-butyl ester (2.37 g, 11.44 mmol) in 5 N HCl in isopropanol (40 mL) is stirred at 80° C. for 3 h. The solvent is evaporated and the crude product is purified by MPLC on silica gel (heptane:EA gradient) to give 2,6-dimethylisonicotinic acid hydrochloride as a beige resin; 1H NMR (CD3OD): δ 8.16 (s, 2H), 2.84 (s, 6H).
