Versuchsvorschrift
A solution of 6-methyl-5-isobutyl-nicotinic acid tert.-butyl ester (0.50 g, 2 mmol) is dissolved in dioxane (20 mL) and 4 N HCl in dioxane (30 mL) is added. The mixture is stirred for 3 h. The solvent is evaporated to give 6-methyl-5-isobutyl-nicotinic acid hydrochloride (0.52 g); LC-MS: tR=0.54 min; [M+1]+=194.29; 1H NMR (d6-DMSO) δ 0.91 (d, J=6.5 Hz, 6H), 1.91 (hept, J=6.5 Hz), 2.68 (d, J=7.3 Hz, 2H), 2.73 (s, 3H), 8.47 (d, J=1.8 Hz, 1H), 8.90 (d, J=2.0 Hz, 1H).
