Reaction Conditions:
at 70; for 4 h;
Steps:
4.1.8. N-Methyl-N-(2-pyridyl)acetamide (8)
A mixture of 2-(methylamino)pyridine (857 mg, 7.92 mmol) and acetic anhydride (4.23 g, 41.4 mmol) was heated at 70 °C for 4 h. After removal of the solvent under reduced pressure, chromatography (AcOEt) of the residue gave 8 as a pale brown oil in quantitative yield. νmax (KBr) 1663, 1587, 1379 cm-1; 1H NMR (300 MHz, CD2C12) δ 8.44 (1H, ddd, J 0.8, 2.0, 4.8 Hz), 7.72 (1H, dd, J 2.0, 7.5 Hz), 7.29 (1H, d, J 8.1 Hz), 7.15 (1H, ddd, J 1.0, 4.8, 7.3 Hz), 3.31 (3H, s), 2.03 (3H, s); 13C NMR (75 MHz, CDC13, 55 °C) δ 170.7, 156.5, 148.9, 138.0, 121.5, 120.3, 35.4, 23.0; m/z (EI) 150; HRMS (EI): M+, found 150.0807.
