Procedure

A solution of 2-anilino-7-chloro-5-methyl-1-phenyl-1,8-naphthyridin-4(1H)-one (95.0 mg, 0.263 mmol), TEA (0.65 mmol), and 10% Pd/C in EtOAc (2.5 mL) and EtOH (2.5 mL) was stirred under H2 (1 atm) for 3.5 h. The reaction mixture was filtered through a pad of Celite using EtOH and EtOAc to rinse. The combined filtrates were concentrated in vacuo, and purified with Biotage silica gel chromatography using 1:1 EtOAc:Hex to afford 2-anilino-5-methyl-1-phenyl-1,8-naphthyridin-4(1H)-one (84 mg, 98%) as a pale yellow solid. LCMS RT: 2.26 min, MH+: 328.4, Rf=0.1 (1:1 EtOAc:Hex),
