실험 절차
The solution of quinoline-3-carboxylic acid (3 g, 17.32 mmol) in methanol (30 mL) was cooled on ice bath at 0° C. Then thionyl chloride (1.264 mL, 17.32 mmol) was added and the reaction mixture was heated to 80° C. and maintained overnight. Reaction was monitored by TLC. After completion of reaction methanol was evaporated under reduced pressure and the resultant residue was basified with saturated sodium bicarbonate to make pH (7 to 8) to get white solid which was filtered and dried to get methyl quinoline-3-carboxylate (3.2 g, yield-99%) as a white solid; m/z-187.3.
