The synthetic route is as follows., Quality Control of 1-Methyl-3-(trifluoromethyl)-1H-pyrazole-5-carboxylic acid
Synthesis of 1-methyl-3-(trifluoromethyl)-1 H-pyrazole-5-carboxamide[0230] 1-Methyl-3-(trifluoromethyl)-1 H-pyrazole-5-carboxylic acid (4.85 g) and dimethylformamide (0.04 g) were dissolved in dichloromethane (80 ml), and a dichloromethane solution (20 ml) of oxalyl chloride (3.33 g) was dropped thereon. The mixture was stirred at room temperature for 1 hour, and then, the solvent was concentrated. The residue was dissolved in dichloromethane (15 ml), and a mixed solution of 28% ammonia water (15.2 g) and dichloromethane (25 ml) was added thereto at 0C. The mixture was stirred at room temperature for 1 hour, and then, the organic layer was separated and dried over anhydrous magnesium sulfate. The solvent was concentrated to obtain crude 1-methyl-3- (trifluoromethyl)-1 H-pyrazole-5-carboxamide (4.29 g).
