HCID 67254019, compound → Methyl 4-methyl-5-(2-(trifluoromethyl)phenyl)-1H-pyrrole-3-carboxylate

Participants

Reaction Steps

To a solution of 4-methyl-5-(2-trifluoromethyl-phenyl)-2,3-dihydro-1H-pyrrole-3-carboxylic acid methyl ester (10 g, 35 mmol) in toluene was added 10% Pd/C (3.3 g). The resulting suspension was heated to reflux for 3 days. After cooling, the solids were removed by filtration. The filtrate was washed with toluene and concentrated under reduced pressure to yield an oil, which was purified by column chromatography (silica), eluting with EtOAc-hexane (1:1) to give the title compound (2.9 g, 29%). MS (ES): 284 (MH+).
