Some tips on C7H7F3N2O2

The synthetic route of 345637-71-0 has been constantly updated, and we look forward to future research findings.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 345637-71-0, name is 2-(5-Methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl)acetic acid, A new synthetic method of this compound is introduced below., Computed Properties of C7H7F3N2O2

To a stirred solution of (5-methyl-3-trifluoromethyl-pyrazol-l-yl)acetic acid (0.0885 g, 0.4255 mmol) in dichloromethane (10 mL) was added oxalylchloride (0.108 g, 0.851 mmol) and drop a of DMF. The reaction mixture was stirred at 45 C for 2 h, and then concentrated under reduced pressure to provide the title compound as a white solid (0.096 g)..H NMR (CDCI3): delta 6.38 (s, 1H), 5.27 (s, 2H), 2.31 (s, 3H).

The synthetic route of 345637-71-0 has been constantly updated, and we look forward to future research findings.
