Procedure

To 20 ml of N-methylpyrrolidone were added 9.7 g of 2-(t-butylamino)-3,5,6-trifluoropyridine together with 15.5 g of benzylamine, and the mixture was stirred at 160° C. for one day and allowed to cool. After adding 50 ml of chloroform, the mixture was washed three times with 500 ml of distilled water. The chloroform layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure to obtain about 16.5 g of the title compound as a dark green oil.
