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