To a solution of 2-(2-{4-[6-(methyloxy)-1,5-naphthyridin-4-yl]-2-oxo-1-piperazinyl}ethyl)-1H-isoindole-1,3(2H-dione (100 mg, 0.232 mmol) in EtOH (2 mL) was added hydrazine hydrate (120 μL, 3.85 mmol). After 2 h at 85° C., the solution was concentrated and the residue purified by column chromatography (silica, 5-10% MeOH in DCM (1% NH4OH)) yielding the title compound (46 mg, 66%) as a yellow oil: LCMS (ES) m/e 302 (M+H)+.
