Procedure

2-anilino-6-fluoro-7-(hydroxymethyl)-1-phenyl-1,8-naphthyridin-4(1H)-one (62 mg, 0.175 mmol) was dissolved in CH2Cl2 (1.2 mL). 4-methoxyphenol (22 mg, 0.175 mmol) was added followed by Ph3P (91.8 mg, 0.35 mmol), and ADDP (88.31 mg, 0.35 mmol). The reaction was left to stir overnight at room temperature under argon. Hexanes (5 mL) were added and the reaction was filtered. The filtrate was concentrated in vacuo. Purification of the residue using Biotage silica gel chromatography eluting with 7:3 to 9:1 EtOAc:Hex provided 2-anilino-6-fluoro-7-[(4-methoxyphenoxy)methyl]-1-phenyl-1,8-naphthyridin-4(1H)-one (30.0 mg, 37%) as a white solid: LCMS RT 2.87 min, MH+: 464.2.
