2,2,2-Trifluoro-N-phenylacetamide → Aniline, N-(2,2,2-trifluoroethyl)-

To a solution of 2,2,2-trifluoro-N-phenylacetamide (5.0 g, 26 mmol) in THF (10 mL) was added BH3 in THF (130 mL, 130 mmol, 1.0 M). The resulting mixture was refluxed overnight. The mixture was quenched with water and methanol, concentrated to remove most of THF, and extracted with EtOAc. Organics were washed with brine, dried (Na2SO4), and concentrated to give 4.17 g (92%) of the title compound as a colorless oil. 1H NMR (400 MHz, CDCl3): δ 3.71-3.75 (2H, m), 6.66 (2H, d, J=8.0 Hz), 6.79 (1H, t, J=7.2 Hz), 7.20 (2H, t, J=8.0 Hz).
