Reaction Steps

42 mg of 6-({4-[4-(2-chloroethyl)piperazin-1-yl]phenyl}amino)-4-[(3,5-difluorobenzyl)amino]pyridine-3-carboxyamide (the compound of Example 250) was dissolved in a 30% methylamine-ethanol solution, to which 23 mg of potassium carbonate was added, and stirred at 80° C. for 8 hours. After cooling, water was added to the reaction mixture, 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:ammonia methanol=10:1), and crystallized by adding ether to obtain 8 mg (15%) of the title compound as a slight yellow solid.
