Participants

Reaction Steps

60 mg of 6-({4-[4-(2-aminoethyl)piperazin-1-yl]phenyl}amino)-4-[(3,5-difluorobenzyl)amino]pyridine-3-carboxyamide (the compound of Example 248) was suspended in 6 mL of chloroform, to which, under ice cooling, 20 mg of pyridine and 17 mg of methanesulfonyl chloride were added, and stirred at the same temperature for 20 minutes. To the reaction mixture, ammonia water was added, extracted with chloroform, the extract was washed with saturated saline, and dried on anhydrous sodium sulfate. The solvent was evaporated, and the residue was purified by silica gel thin layer chromatography (chloroform:methanol=5:1), recrystallized from chloroform-methanol-ether to obtain 40 mg (57%) of the title compound as a slight yellow crystalline powder.
