Procedure

Trifluoroethanol (0.08 mL, 1.1 mmol) was added to a suspension of NaH (60% oil dispersion, 44 mg, 1.1 mmol) in DMSO (4 mL) at 0° C., and the mixture was heated at 60° C. for 1 h. The mixture was cooled to room temperature and a solution of 2-anilino-5-chloro-7-methyl-1-phenyl-1,6-naphthyridin-4(1H)-one (200 mg, 0.55 mmol) in DMSO (2 mL) was added. The resulting mixture was stirred at 50° C. for 16 h. The reaction mixture was cooled, poured into ice water and extracted with CH2Cl2. The organic layer was washed with brine, dried over MgSO4, and concentrated in vacuo. The residue was purified by a Biotage silica gel chromatography (2:1 EtOAc:Hex) to provide 2-anilino-7-methyl-1-phenyl-5-(2,2,2-trifluoroethoxy)-1,6-naphthyridin-4(1H)-one (159 mg, 68%): LCMS RT: 2.65 min, MH+: 426.4. This transformation can be accomplished by using other aprotic solvents such as DMF, THF and dioxane with temperatures appropriate for these solvents. Commercially available alkoxides can also be used in the absence of base.
