Yield:173261-76-2 75%
Reaction Conditions:
with silver carbonate at 50; for 16 h;
Steps:
Ethyl 6-methoxy-2-methylnicotinate
: To a suspension of ethyl2-methyl-6-oxo-1,6-dihydropyridine-3-carboxylate (0.2 g, 1.06 mmol) and Ag2CO3(0.44 g, 1.59 mmol) was added methyl iodide (0.3 mL, 4.24 mmol)and the reaction mixture was heated at 50 °C for 16 h. The reaction mixture wascooled to room temperature, filtered and concentrated. The crude residue waspurified by Combiflash with 20% EtOAc in Hexane to afford the title compound asoff-white solid (0.25 g, 75%). 1H NMR (DMSO-d6, 400 MHz) δ1.37 (t, J = 7.2 Hz, 3H), 2.75 (s,3H), 3.96 (s, 3H), 4.33 (q, J = 7.2Hz, 2H), 6.57 (d, J = 8.4 Hz, 1H),8.11 (d, J = 8.8 Hz, 1H); MS (ESI) m/z196.1 (M+H)+.
