Procedure

Aqueous NaOH (2N, 1 mL) was added to a stirred solution of ethyl[(2-anilino-7-methyl-4-oxo-1-phenyl-1,4-dihydro-1,6-naphthyridin-5-yl)sulfanyl]acetate (100 mg, 0.23 mmol) in EtOH (8 mL) at room temperature. The mixture was allowed to stir for 4 h and was concentrated in vacuo. The reaction mixture was acidified with 1N HCl and extracted with CH2Cl2. The organic layer was dried over MgSO4 and concentrated in vacuo. Purification by reverse-phase preparative HPLC (10% CH3CN in water with 0.1% TFA to 95% CH3CN in water, 10 mL/min, 10 min) provided [(2-anilino-7-methyl-4-oxo-1-phenyl-1,4-dihydro-1,6-naphthyridin-5-yl)sulfanyl]acetic acid (56 mg, 60%): LCMS RT: 2.61 min, MH+: 418.2.
