Reaction Steps

8-chloro-2-(2-(quinolin-2-yl)ethyl)pyrido[4,3-d]pyridazin-1(2H)-one (34 mg, 0.101 mmol) was suspended in 2 mL of toluene and 2 mL of methanol under argon. Then, an aqueous solution of sodium carbonate (16.5 mg, 0.15 mmol, 2 M) was added. To the suspension, pyridin-4-boronic acid (13.79 mg, 0.101 mmol) and then tetrakis(triphenylphosphine)palladium(0) (11.67 mg, 10.10 μmol) were added. The reaction mixture was heated in a CEM microwave at 130° C. for 30 min. Water and EA were added. The organic phase was extracted with water, dried (MgSO4) and evaporated. The residue was purified by chromatography (eluent: DCM/methanol) and then recrystallized from EA/diisopropyl ether (1:1) to give 2.6 mg (yield: 6.79%) of the title compound as off-white solid. LC-MS: m/e 380.1 (M+H)+
