Reaction Steps
To a solution of 2-(1-(5,7-difluoroquinolin-6-yl)ethyl)isoindoline-1,3-dione (2.6 g, 7.7 mmol) in CH3OH (50 mL) was added hydrazine monohydrate (0.38 g, 7.7 mmol). The solution was heated at 50° C. and stirred overnight. After cooling and evaporating, the residue was purified by silica gel and eluted with hexane/EtOAc to give the title compound (1.0 g, 60%). 1H-NMR (400 MHz, DMSO-d6) δ ppm 8.95 (d, 1H), 8.45 (d, 1H), 7.65 (d, 1H), 7.60 (dd, 1H), 4.49 (q, 1H), 2.20 (bs, 2H), 1.48 (d, 3H).
