Reaction Steps

2-(Pyrrolidin-1-yl)-2-(3,4-dichlorophenyl)ethylamine. A slurry of αPyrrolidin-1-yl-3,4-dichlorobenzyl cyanide hydrochloride salt (4.73 g) in tetrahydrofuran (100 mL) was added to a slurry of lithium aluminum hydride (3.23 g) in tetrahydrofuran (35 mL) while maintaining a reflux. The reaction was allowed to reflux 18 hours. The reaction was cooled in an ice bath and treated with aqueous sodium sulfate. The reaction was filtered and evaporated to give a reddish-brown oil. The oil was dissolved in diethylether, treated with hydrochloric acid (g)/diethylether, and evaporated to a red oil which was used directly in subsequent reactions.
