Reaction Conditions

Reaction Steps

To 5 ml of N-methylpyrrolidone were added 1.8 g of 4-(t-butylamino)-2-chloro-5-fluoropyrimidine and 4.0 g of benzylamine, and the mixture was stirred at 140° C. for 17 hours and separated by adding 300 ml of distilled water and 40 ml of chloroform. The chloroform layer was washed twice with 300 ml of distilled water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The precipitated pale yellow crystals were dispersed in diisopropylether and collected by filtration to obtain 1.9 g of the title compound.
