Reaction Steps

To a slurried 2-((S)-1-(7-fluoro-2-(pyridin-2-yl)quinolin-3-yl)ethyl)isoindoline-1,3-dione (2.1 g, 5.3 mmol) in anhydrous ethanol (15 mL) was added NH2NH2 (0.85 g, 26 mmol) dropwise over 5 minutes. The reaction mixture was heated to 90° C. for 30 min and cooled to rt. The reaction mixture was filtered and washed with EtOAc. The resulting EtOAc solution was washed with water, brine and dried over Na2SO4. Removal of solvents gave a tan oil of (S)-1-(7-fluoro-2-(pyridin-2-yl)quinolin-3-yl)ethanamine (1 g, 71%). Mass Spectrum (ESI) m/e=468 (M+1).
