A suspension of 6-chloro-2-(2-(7-methoxyquinolin-4-yloxy)ethyl)pyridazin-3(2H)-one (1250 mg, 3768 μmol), (4-aminomethylphenyl)boronic acid, hydrochloride (1412 mg, 7536 μmol), Na2CO3 (7536 μL, 15071 μmol) [2M], and [1,1′-bis(diphenylphosphino)ferrocene]dichloride palladium(II) complex with dichloromethane (276 mg, 377 μmol) in DME (2 mL) was sparged with argon for 5 minutes then heated to 85° C. for 4 hours. The reaction was then partitioned between DCM (50 mL) and 1 M NaOH (20 mL). The organic was dried over MgSO4, concentrated onto dry silica (10 g) then purified on silica (40 g) eluting with 0>5% MeOH/DCM. The product was isolated as an off white solid from ACN.
