Reaction Steps

To a solution of N-(4-(3-chloro-2-(diphenylmethyleneamino)pyridin-4-yloxy)-3-fluorophenyl)-5-(4-fluorophenyl)-4-oxo-1,4-dihydropyridine-3-carboxamide (Preparation 1G, 127 mg, 0.2 mmol) in EtOH (5 mL) and THF (5 mL) at 0° C., was added NaBH4 (300 mg, 7.93 mmol). The mixture was stirred at 0° C. for 3 h, and then at rt overnight. The reaction was quenched with water, extracted with DCM, and dried over MgSO4. After filtration and concentration in vacuo, 120 mg of the desired material was obtained as a white solid. MS (ESI+) m/z 635 (M+H)+.
