To the stirring solution, cooled to 0° C., was added DIEA (202 μl, 1.158 mmol). This solution was added dropwise to a 0° C. mix of DMF (1 ml) and 3-aminophenyl acetamide. The reaction was stirred at 0° C. for min and then at RT for 1 h. The reaction mix was diluted with EtOAc and water. The layers were separated, and the aqueous layer was extracted twice with EtOAc. The combined organic layer was washed 3 times with brine, dried over Na2SO4, and concentrated under reduced pressure, giving 2-[3-(4-chloro-[1,3,5]triazin-2-ylamino)-phenyl]acetamide.
