Reaction Steps

5-Chloro-2-methyl-nicotinic acid (4.15 g, 24.2 mmol) was placed in a flask with DCM (100 ml) and oxalyl chloride (3.68 g, 29 mmol). DMF (200 μl) was added and the reaction mixture was stirred at RT for 1 hour (gas evolution). The mixture was filtered and the solvent was removed in vacuo to afford the title product which was used without further purification.
