Reaction Steps

To a chilled solution of methyl 2-pyrrolecarboxylate (500 mg, 4.0 mmol) in dry DMF (15 mL) was added sodium hydride (60% dispersion in mineral oil, 300 mg, 7.5 mmol) portion wise. The mixture was stirred at 0° C. for 1 hour and a solution of 2-bromo-1-[4-(hydroxymethyl)phenyl]ethanone (750 mg, 3.3 mmol) in DMF (5 mL) was added and the mixture was allowed to warm to room temperature and stirred for 1.5 hour. A saturated aqueous solution of NH4Cl (35 mL) was added followed by EtOAc (100 mL). The organic layer was then washed with brine (35 mL), dried (MgSO4), filtered and concentrated in vacuo to yield a oil. The material was purified by flash chromatography (Biotage SP4, 40 g cartridge, gradient 0-80% EtOAc in hexanes) to give methyl 1-{2-[4-(hydroxymethyl)phenyl]-2-oxoethyl}-1H-pyrrole-2-carboxylate as a white solid (150 mg, yield: 17%). ESI-MI m/z [M+H]+: 273.8.
