Reaction Steps
To a stirred solution of 60% NaH (in mineral oil) (18.27 g, 0.458 mol, Aldrich, India) in DMSO (66 mL, Spectrochem., India) at 0° C., was added 6-methylpyridin-3-ol (25.0 g, 0.229 mol) dissolved in DMSO (100 mL) drop wise over a period of 15 min. After complete addition, the reaction mixture was stirred at 0° C. for 40 min. Methyl iodide (29.5 mL, 0.458 mol, Spectrochem, India) was added and the reaction mixture was stirred at rt for 2 h. The reaction with water and Et2O (1:1, 200 mL). The organic layer was separated and aqueous layer was back extracted with Et2O (75 mL×3). The organic layers were combined, dried over anhydrous sodium sulfate and concentrated to give the title compound as a dark brown gummy oil. 1H NMR (400 MHz, CDCl3) δ ppm 8.19 (d, J=2.8 Hz, 1H), 7.12-7.05 (m, 2H), 3.83 (s, 3H), 2.49 (s, 3H). MS (ESI, positive ion) m/z: 124.0 (M+H).
