Reaction Steps

To a stirred mixture of 1.9 g (0.005 mole) of 1-[4,5-bis(4-methoxyphenyl)-1H-pyrrol-2-yl]-2,2,2-trifluoro-1-ethanone and 25 ml ethanol at 0° was added 0.4 g (0.01 mole) of sodium borohydride all at once. The mixture was stirred at 0° 0.5 hour, then at room temperature 1 hour. The mixture was chilled in an ice bath and 40 ml of 1N hydrochloric acid was added dropwise. The mixture was poured into water and extracted with methylene chloride. The organic layers were dried and concentrated. The crude solid was triturated with methylcyclohexane and collected to give 1.6 g of product, m.p. 84°-86°.
