Versuchsvorschrift

To a stirred solution of 1-phenyl-cyclopentanecarbonitrile (4 g, 23.5 mmol) in tetrahydrofuran (50 mL) was added lithium aluminium hydride slowly (1M in tetrahydrofuran, 70 ml, 70.6 mmol) and the reaction mixture was stirred at room temperature for 2 h. After completion of the reaction, the reaction mixture was quenched with saturated aqueous Na2SO4 solution slowly at 0° C. It was then filtered and the residue was washed with ethyl acetate. The organic part was concentrated to get C-(1-phenyl-cyclopentyl)-methylamine (8) (2.5 g, crude) as a liquid.
