Reaction Steps

A 0.5-2 mL microwave vial was charged with 1-(4-(3-(aminomethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)-2-fluorophenyl)pyrrolidin-2-one (0.0792 g, 0.243 mmol), 8-chloro-3-methoxy-1,5-naphthyridine (0.0590 g, 0.303 mmol), and butan-2-ol (1.00 ml, 0.243 mmol), sealed, then placed in a Personal Chemistry Microwave for 4 hours at 120° C. The mixture was concentrated, then triturated with MeOH to give 1-(2-fluoro-4-(3-((7-methoxy-1,5-naphthyridin-4-ylamino)methyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)phenyl)pyrrolidin-2-one as the hydrochloric salt.
