The synthetic route is as follows., Recommanded Product: 478968-48-8

A mixture of CuT (122.93 mg, 0.65 mmol, 0.10 equiv), L-proline (148.8 mg, 1.29 mmol, 0.20 equiv), potassium carbonate (1.786 g, 12.92 mmol, 2.00 equiv), ethyl 3-methoxy-1H-pyrazole-4- carboxylate (1.1 g, 6.46 mmol, 1.00 equiv), and 5-bromo-2-(trifluoromethyl)pyridine (2.185 g, 9.67 mmol, 1.50 equiv) in DMSO (60 mL) was stuffed overnight at 100C under nitrogen. The reaction solution was diluted with water and extracted with ethyl acetate. The combined extracts were washed with brine, dried over anhydrous sodium sulfate, and concentrated under vacuum. The residue was purified by a silica gel column with ethyl acetate/petroleum ether (1:6) to afford the title compound (790 mg, 39%) as a white solid.

According to the analysis of related databases, 478968-48-8, the application of this compound in the production field has become more and more popular.
