Versuchsvorschrift
A solution of 2-fluoro-4-nitrobenzonitrile (0.541 g, 2.43 mmol) in methanol (20 mL) and 6N hydrochloric acid (3 mL) was hydrogenated (55 psi) over 10% palladium on carbon (164 mg) for 22 h. The reaction mixture was filtered and concentrated in vacuo to afford 77A (0.65 g, 100%). 1H NMR (400 MHz, CD3OD) δ 4.23 (s, 2H), 7.29 (d, J=8.79 Hz, 2H), 7.68 (t, J=7.91 Hz, 1H).
