Versuchsvorschrift

To a solution of (S)-2-(2-fluoro-1-phenylethyl)isoindoline-1,3-dione (290 mg, 1.077 mmol) in MeOH (3.59 mL) was added hydrazine (0.507 mL, 16.15 mmol). The reaction mixture was stirred at 80° C. for 3 h. The white precipitate was filtered off. The filtrate was concentrated to yield the crude (S)-2-fluoro-1-phenylethanamine, which was used in next step without further purification. LCMS (m/z): 140.1 (MH+), 0.28 min; 1H NMR (400 MHz, CDCl3) δ ppm 7.43-7.34 (m, 4H), 7.34-7.27 (m, 1H), 4.57 (dd, J=3.7, 8.8 Hz, 1H), 4.49-4.38 (m, 1H), 4.38-4.32 (m, 1H), 4.32-4.25 (m, 1H).
