実験手順
To a solution of 2-amino-N-benzylisonicotinamide (0.23 g, 0.43 mmol), dimethylaminopyridine (0.01 g, 0.08 mmol) and N,N-diisopropylethylamine (0.3 mL, 1.7 mmol) in tetrahydrofuran (10 mL) at 0° C. was added benzoyl chloride (0.12 mL, 1.00 mmol). The resulting solution was warmed to ambient temperature and stirred for 18 hours, diluted with ethyl acetate (30 mL), washed with water (20 mL) and brine (20 mL). The organic solution was dried over anhydrous sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography to give 2-benzamido-N-benzylisonicotinamide (0.02 g, 15%): mp 174-176° C.; 1H NMR (300 MHz, CDCl3) δ 8.86 (br s, 1H), 8.72 (s, 1H), 8.38 (d, J=5.1 Hz, 1H), 7.91-7.82 (m, 2H), 7.60-7.32 (m, 9H), 6.73 (br s, 1H), 4.64 (d, J=5.7 Hz, 2H); 13C NMR (75 MHz, CDCl3) δ 165.9, 165.0, 151.9, 148.3, 144.4, 137.4, 133.5, 132.7, 129.0, 128.8, 128.0, 127.8, 127.2, 118.6, 110.5, 44.3; MS (ES+) m/z 332.5 (M+1).
