Procedure

To a 0° C. solution of 3-(1H-indol-6-yl)-3-phenyl-propionitrile XIII (1.1 g, 4.5 mmol) in THF (35 ml) was slowly added a suspension of LiAlH4 (0.51 g, 13 mmol) in THF (10 ml). The mixture was stirred 10 min at 0° C. and 10 minutes at room temperature, then it was refluxed for 1.5 hours. The reaction mixture was cooled to 0° C., quenched by the careful addition of freshly ground Na2SO4.10H2O (25 g), filtered, and the solid was washed with EtOAc. The filtrate was concentrated and purified via flash chromatography (DCM/MeOH/NH4OH) affording 3-(1H-indol-6-yl)-3-phenyl-propylamine XIV as a colorless oil (0.68 g, 62% yield).
