Compound A (1.53 g, 6.25 mmol), 2-(3-fluorophenoxy)ethylamine hydrochloride (1.79 g) and sodium hydrogencarbonate (5.25 g) were added to DMSO (30 ml), and the mixture was stirred at 100° C. for 27 hr. After stirring, the reaction mixture was added dropwise 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 purified by silica gel chromatography. This was converted to hydrochloride to give the object compound of 2-(2-(3-fluorophenoxy)ethylamino)-6-(5-methyl-1H-pyrazol-3-ylamino)-4-methylnicotinonitrile hydrochloride (308 mg).
