29 mg of 6-chloro-4-[(3,5-difluorobenzyl)amino]pyridine-3-carboxyamide (the compound of Example 20) and 35 mg of 4-(tetrahydro-2H-pyran-4-yl)aniline were dissolved in 0.35 mL of 1,4-dioxane, to which 8.0 mg of [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (II) complex with dichloromethane, 17 mg of 1,1′-bis (diphenylphosphino)ferrocene and 12 mg of sodium tert-butoxide were added, and stirred using a microwave reaction apparatus under an argon atmosphere at 100° C. for 1 hour. After cooling, the solvent was evaporated and the residue was purified by silica gel thin layer chromatography (chloroform:methanol=20:1) to obtain 7 mg (16%) of the title compound as a white crystalline powder.
