Participants

Reaction Steps

A 750 mg portion of ethyl 5-tert-butyl-1-[2-(4-fluorophenyl)ethyl]-4-formyl-2-methyl-1H-pyrrole-3-carboxylate was suspended in 15 ml of ethanol, and 158 mg of sodium borohydride was added at 0° C., followed by stirring at room temperature for 2 hours. The solvent was evaporated under a reduced pressure, chloroform and water were added, and the organic layer was washed with saturated brine and then dried over anhydrous sodium sulfate. By evaporating the solvent under a reduced pressure, 754 mg of ethyl 5-tert-butyl-1-[2-(4-fluorophenyl)ethyl]-4-(hydroxymethyl)-2-methyl-1H-pyrrole-3-carboxylate was obtained as a colorless solid.
