Procedure
To 10 ml of N-methylpyrrolidone were added 6.8 g of 4-(t-butylamino)-2,3,5,6-tetrafluoropyridine together with 7.2 g of benzylamine, and the mixture was stirred at 115° C. for one day and allowed to cool. After adding 40 ml of chloroform, the mixture was washed three times with 400 ml of distilled water. The chloroform layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure to obtain about 8.0 g of the title compound as a dark green crude oil.
