A 10-20 mL microwave vial was charged with hydrazine hydrate (0.0312 ml, 0.642 mmol), (6-phenylimidazo[1,2-b]pyridazin-3-yl)(quinolin-6-yl)methanone (0.150 g, 0.428 mmol), KOH (0.0961 g, 1.71 mmol), and diethylene glycol (4.09 ml, 42.8 mmol), sealed, then placed in a Personal Chemistry microwave at 130° C. for 20 minutes after a 5 minute pre-stir. The mixture was diluted with water (75 mL), then extracted with DCM (2×75 mL). The combined organics were washed with brine (75 mL), then dried with MgSO4, filtered, and concentrated to give a brown solid, then purified by prep HPLC to give the product as the formic acid salt. MS (ESI pos. ion) m/z: 337 (MH+). Calc'd exact mass for C22H16N4: 336.
