Reaction Steps

To a stirred solution of 2-(4-amino-phenyl)-propionic acid ethyl ester (5.0 g, 25.9 mmol, Takahashi, I. et al., Heterocycles 1996, 43, 2343–2346.) in tetrahydrofurane (200 ml) was slowly added lithiumaluminium hydride (1.96 g, 51.8 mmol), and the mixture was stirred at room temperature for 14 h. The reaction mixture was quenched with 25% ammonia solution (50 ml) under ice-bath cooling. The resulting precipitate was filtered off, and the filtrate concentrated under reduced pressure to afford 3.88 g (99%) of the title compound as slight brown syrup.
