실험 절차
A solution of 6-isobutyl-5-methyl-nicotinic acid ethyl ester (2.86 g, 12.9 mmol) in 7 N NH3 in MeOH (80 mL) is stirred at 60° C. for 20 h before the solvent is removed in vacuo. The residue is dried to give 6-isobutyl-5-methyl-nicotinamide (1.89 g) as a yellow oil; LC-MS: tR=0.66 min, [M+1]+=193.29; 1H NMR (D6-DMSO): δ 0.91 (d, J=6.5 Hz, 6H), 2.08-2.20 (m, 1H), 2.32 (s, 3H), 2.65 (d, J=7.3 Hz, 2H), 7.43 (s, 1H), 7.95 (s, 1H), 8.01 (m, 1H), 8.78 (s, 1H).
