실험 절차

A round-bottom flash was charged with 4-iodo-1-methyl-1H-pyrazole-5-carboxylic acid (297 g, 1.18 mol), DCM (2.97 L), and 1,1′-carbonyldiimidazole (CDI) (207 g, 97% by mass, 1.24 mol). The reaction mixture was stirred at room temperature for 45 min. Ammonium chloride (189 g, 3.53 mol) and triethylamine (498 mL, 3.53 mol) were added and the reaction mixture was stirred at room temperature overnight. The reaction mixture was concentrated in vacuo and the residue was suspended in H2O (˜3 L) and granulated at room temperature for 1 h. The solid was collected via filtration, washed with H2O, and dried in a vacuum oven to afford 4-iodo-1-methyl-1H-pyrazole-5-carboxamide as a colorless solid (222 g, 75% yield).
