実験手順
A stirred solution of 100 mg of 2,2-difluoro-2-(2-pyridyl)ethyl azide was hydrogenated in 10 ml of ethyl acetate over 100 mg of 10% palladium on carbon under a balloon of hydrogen for 1 h. The catalyst was removed by filtration and the solvents removed at reduced pressure to give 1-10 as a yellow oil: 1H NMR (CDCl3) δ6 8.66 (d, 1H, 4.2 Hz), 7.82 (td,1H, 7.7, 1.7 Hz), 7.68 (d, 1H, 8.1 Hz), 7.37-7.40 (m, 1H), 3.44 (t, 2 H, 14.3 Hz), 1.41 (br s, 2H).
