Reaction Conditions

Reaction Steps

To 4.1 g of N-methylpyrrolidone were added all amount of the 2,3,5-trifluoro-6-isopropylaminopyridine as described above together with 3.1 g of p-methoxybenzylamine, and the mixture was stirred at 150° C. for 15 hours and allowed to cool. After adding 50 ml of the mixed solution of 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 3.9 g of the title compound as a brown crude oil.
