Procedure

To a suspension of methyl 4-(4-chloro-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoate (600 mg) in THF (20 mL) was added tert-butyl 8-aminooctylcarbamate hydrochloride (465 mg) and iPr2NEt (0.578 mL). The mixture was heated at 70° C. for 16 hours. The solvent was removed under vacuum. The residue was purified by silica gel column (EtOAC/Hexanes=4:1) to give methyl 4-(4-(8-(tert-butoxycarbonylamino)octylamino)-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoate (0.57 g).
