Into a 25-mL round-bottom flask, was placed methyl 1-(4-chlorophenyl)-3-(trifluoromethyl)-1H-pyrrole-2-carboxylate and methyl 1-(4-chlorophenyl)-3-(perfluoroethyl)-1H-pyrrole-2-carboxylate (200 mg, 0.66 mmol, 1.00 equiv), LAH (50 mg, 1.32 mmol, 2.00 equiv) and tetrahydrofuran (5 mL). The resulting solution was stirred for 2 h at 0° C. in a water/ice bath. The reaction was then quenched by the addition of 3 mL of water. The resulting solution was extracted with ethyl acetate (5×10 mL) and the organic layers combined. The resulting residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:6) to yield [1-(4-chlorophenyl)-3-(trifluoromethyl)-1H-pyrrol-2-yl]methanol and (1-(4-chlorophenyl)-3-(perfluoroethyl)-1H-pyrrol-2-yl)methanol as yellow oil.
