Procedure

A mixture of N-{[(2-{4-[(3-amino-4,6-dimethyl-2-pyridinyl)amino]phenyl}ethyl)amino]carbonyl}-4-methylbenzenesulfonamide (300 mg , 0.66 mmol), methylisothiocyanate (56 □l, 0.86 mmol), and THF (6 ml) was stirred at room temperature for 3 days. The solvent was removed to give N-{[(2-{4-[(4,6-dimethyl-{[(methylamino)carbonothioyl]amino}-2-pyridinyl)amino]phenyl}ethyl)amino]carbonyl}-4-methylbenzenesulfonamide [MS (ESI) m/z: 527 ([M+H]+), 525 ([M−H]−)]. This was dissolved with MeCN (4 ml) and treated with Mel (54□□l) at 0° C. for 20 hours. After concentration under reduced pressure, the residue was purified by preparative TLC (EtOAc/EtOH=20/1) to afford 170 mg (52%) of the title compounds.
