To a solution of 4-((4-((4-((2-(chloromethyl)allyl)oxy)benzyl)amino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-yl)amino)benzoic acid (1.1 g) and TBTU (0.74 g) in NMP (10 mL) was added tert-butyl(3-amino-2,2-dimethylpropyl)carbamate (0.51 g) and DIPEA (1.47 mL). After stirring at room temperature for 2 hours, the mixture was diluted with 100 mL of water and extracted with EtOAc (2×150 mL). The organic layer were combined, washed with brine (100 mL), dried over MgSO4 and concentrated. The residue was purified by silica gel column to give tert-butyl 3-(4-(4-(4-(2-(chloromethyl)allyloxy)benzylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzamido)-2,2-dimethylpropylcarbamate (1 g).
