実験手順

14.7 g (0.0734 mole) (3RS)-1-benzyl-3-cyanomethyl pyrrolidine dissolved in 220 ml diethyl ether was slowly added to a slurry of 2.94 g of lithium aluminium hydride in 74 ml diethyl ether under an argon atmosphere. The mixture was stirred over night,and 6 ml water, 18 ml 3.75M NaOH-solution and 6 ml water was added to the mixture. The slurry was dried from excess of water with Na2SO4 /cellite, filtered by suction and evaporated to yield 14.84 g (99%) of the product.
