Reaction Steps

To an acetonitrile solution (5 ml) of 2-methylnicotinic acid (400 mg, 2.92 mmol) and DMF (11.2 μl, 0.156 mmol), oxalyl dichloride (501 μl, 5.83 mmol) was added dropwise, followed by stirring at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure, to obtain a crude product of 2-methylnicotinic acid chloride as a yellow liquid (470 mg).
