Procedure

A mixture of 5-methyl-1-phenyl-2-phenylamino-7-piperazin-1-yl-1H-[1,8]naphthyridin-4-one (22.6 mg, 0.055 mmol) and MsCl (0.083 mmol, 0.006 mL) in CH2Cl2 (0.8 mL) was stirred at room temperature overnight at which time the solvent was removed in vacuo. The resulting residue was purified by prep-TLC to give 7-(4-methanesulfonyl-piperazin-1-yl)-5-methyl-1-phenyl-2-phenylamino-1H-[1,8]naphthyridin-4-one (3.4 mg, 6%): LCMS RT: 2.36 min, MH+: 490.3.
