Reaction Steps

To 2 ml of N-methylpyrrolidone was added 510 mg of 2-amino-5-chloro-3,6-difluoropyridine and 910 mg of p-methoxybenzylamine, and the mixture was stirred at 150° C. for one day, and allowed to cool. After adding a mixed solution of 60 ml benzene and n-hexane (1:1, v/v), the solution was washed twice with 400 ml of distilled water. The organic layer was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to obtain 960 mg of the title compound as a brown crude oil.
