Reaction Steps
Into a 100-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed methyl 3-(trifluoromethyl)-1H-pyrrole-2-carboxylate (810 mg, 4.19 mmol, 1.00 equiv), phenylboronic acid (1.54 g, 12.63 mmol, 3.01 equiv), Cu(OAc)2 (1.52 g, 8.37 mmol, 2.00 equiv), pyridine (1.327 g, 16.78 mmol, 4.00 equiv), 4 {acute over (Å)} Molecular Sieves (1.2 g) and dichloromethane (20.0 mL). The resulting solution was stirred for 2 days at 20° C. The reaction progress was monitored by LCMS. The solids were filtered out and the resulting mixture was concentrated under vacuum. The resulting residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:9) to yield methyl 1-phenyl-3-(trifluoromethyl)-1H-pyrrole-2-carboxylate as a pink solid (0.67 g, 59%)
