Procedure

2-Amino-3-(2-fluorophenyl)propionamide was added carefully to a chilled (50°) mixture of LAH (1.0 g, 26.3 mmol) and 20 ml THF under argon. The reaction was then heated at reflux for 10 hrs. The reaction was cooled to 5° C. and carefully treated with Na2SO4.10H2O. The resulting mixture was stirred for 18 hrs, then filtered to remove the solids. The filtrate was concentrated in vacuo to give an amber oil. MS (m/z): 169 (M+H)+; C9H13FN2 requir. 168.19.
