Methyl iodide → 3-Methoxy-6-methyl-2-nitropyridine

Participants

Reaction Steps

To a stirred mixture of 6-methyl-2-nitropyridin-3-ol (5 g, 0.032 mol, Sigma Aldrich) in DMF (50.0 mL) was added K2CO3 (6.72 g, 0.048 mol, S.d.fine chemicals, India). The reaction mixture was stirred for 30 min at room temperature. MeI (9 mL, 0.14 mol, Spectrochem, India) was then added at room temperature, and the reaction mixture was stirred overnight. After completion of the reaction (monitored by TLC, 30% EtOAc in hexane), the reaction mixture was quenched with ice water, following which the solid product precipitated. The solid was collected by filtration and washed with n-hexane to give the title compound. 1H-NMR (400 MHz, DMSO-d6): δ 7.88 (d, J=8.4 Hz, 1H), 7.64 (d, J=8.8 Hz, 1H), 3.92 (s, 3H), 2.44 (s, 3H). MS (ESI, positive ion) m/z: 169 (M+H).
