실험 절차

To a stirring (mechanical stirring) suspension of 12 gm (0.315 mol) of lithium aluminum hydride in THF (600 ml) in a 2000 ml reaction flask at 0° C. (ice-bath), 35 gm (0.20 mol) of phenylcyclopentane carbonitrile in 100 ml THF is added dropwise via an addition funnel. The ice bath is replaced with a heating mantle and the reaction is heated at reflux for 16 hours. The reaction mixture is diluted with 500 ml ether and cooled down to 0° C. The reaction is worked up by adding 50 ml of 15 wt. % NaOH aqueous solution dropwise with vigorous stirring. Then 20 ml water is added and the mixture is stirred for an addition 10 minutes. The resulting two-phase mixture (a colorless liquid and a white precipitate) is filtered and the filtrate dried over anhydrous MgSO4. Filtration and concentration at reduced pressure on a rotary evaporator gave 33 gm of [(phenylcyclopentyl)methyl]amine.
