Procedure
A solution of 2-anilino-5-chloro-7-methyl-1-phenyl-1,6-naphthyridin-4(1H)-one (200 mg, 0.55 mmol) in EtOH (10 mL) was added ethyl 2-mercaptoacetate (0.12 mL, 1.10 mmol) and TEA (0.23 mL, 1.65 mmol). The reaction was heated at reflux for 24 h. The reaction mixture was cooled, concentrated in vacuo, diluted with water and extracted with EtOAc. The combined organic extracts were washed with water, brine, and dried over Na2SO4. Solvents were removed in vacuo and the residue was purified by reverse-phase preparative HPLC (10% CH3CN in water with 0.1% TFA to 95% CH3CN in water, 10 mL/min, 10 min) to provide ethyl[(2-anilino-7-methyl-4-oxo-1-phenyl-1,4-dihydro-1,6-naphthyridin-5-yl)sulfanyl]acetate (120 mg, 49%): LCMS RT: 3.07 min, MH+: 446.2.
