Reaktionsschritte

To a mixture of 3-(4-amino-phenyl)-propionic acid (1.85 g, 11.2 mmol) and tetrahydrofuran′(200 ml), was added lithium aluminum hydride (1.0 g, 26 mmol). After stirring for 3 hours, the mixture was quenched by addition of methanol (5 ml) and concentrated under reduced pressure. The residue was treated with saturated aqueous sodium chloride solution (100 ml) and extracted with ethyl acetate (200 ml). The organic extract was concentrated under reduced pressure to give 3-(4-amino-phenyl)-propan-1-ol (1.5 g, 89% yield).
