The mixture was at rt for 16 h. After cooling to rt, the mixture was diluted with EtOAc, washed with water, and brine. The organic layer was dried over MgSO4 and concentrated. The residue was purified by silica gel chromatography using 40% EtOAc/Hexanes to give tert-butyl 4-(4-(1-(4-(2-ethoxy-2-oxoethoxy)phenyl)cyclopropylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoate (350 mg).
