Procedure

methyl 4-(4-chloro-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)-2-hydroxybenzoate (100 mg, 0.264 mmol), tert-butyl 6-hydroxyhexylcarbamate (68.9 mg, 0.317 mmol), Triphenylphosphine (139 mg, 0.528 mmol), were dissolved in DCM then DIAD (0.103 mL, 0.528 mmol) was added. The reaction was stirred for 16 h. The solvent was removed under vacuum and the crude product was purified by silica gel chromatography using 20% EtOAc/Hexanes. The product fractions were collected and the solvent was removed under vacuum to give 55 mg (36%) methyl 2-(6-(tert-butoxycarbonylamino)hexyloxy)-4-(4-chloro-6-(2,2,2-trifluoroethoxy)-1,3,5-triazin-2-ylamino)benzoate.
