Compound A (400 mg, 1.63 mmol), 2-(pyridin-4-yloxy)ethylamine (540 μl) and sodium hydrogencarbonate (1.32 g) were added to DMSO (12 ml), and the mixture was stirred at 100° C. for 27 hr. After stirring, the reaction mixture was added to cold water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and concentrated, and the residue was washed by suspending in ethyl acetate to give the object compound of 2-(2-(pyridin-4-yloxy)ethylamino)-6-(5-methyl-1H-pyrazol-3-ylamino)-4-methylnicotinonitrile (23 mg).
