Reaction Steps

To a stirring solution of 2-chloro-4-(1-(2-(7-methoxyquinolin-4-yloxy)ethyl)-6-oxo-1,6-dihydropyridazin-3-yl)benzaldehyde (370 mg, 849 μmol) and (trifluoromethyl)trimethylsilane (121 μL, 849 μmol) in DME (10 mL) at −50° C. under nitrogen was added solid tetramethylammonium fluoride (79 mg, 849 μmol). The reaction was then removed from cooling bath and slowly warmed to 0°C. The reaction was then partitioned between DCM (100 mL) and 5% NaHCO3 (50 mL). The organic was dried over MgSO4, concentrated under reduced pressure, then purified on silica (40 g) eluting with 2 to 3% of MeOH/DCM. Product was isolated as an off white solid. MS (ESI pos. ion) m/z: 506 (MH+); calc'd for C24H19ClF3N3O4: 505.
