반응 조건

온도	80 °C

반응 단계

2-Hydroxy-6-methoxy-benzoic acid (87) (0.067 g=0.4 mmol), iPr2EtN (0.6 mmol) and HBTU (0.44 mmol) were dissolved in DMF (2 mL) and shaken in a sealed vial for 25 min. 2-Benzyloxy-N4-(4,6-bis-((3R,5S)-3,5-bis-(tert-butoxycarbonylamino)-piperidin-1-yl)-[1,3,5]triazin-2-yl)-benzene-1,4-diamine (83) (0.184 g, 0.2 mmol) was added and the mixture was heated to 80° C. for 3 h. LC-MS indicated complete coupling at this point. Upon concentrating, the crude product was dissolved in CHCl3 (4 mL), washed with aqueous sat. NaHCO3 (2×2 mL), water (2×2 mL) and concentrated to dryness. Purification by ISCO (15–100% EtOAc/hexanes) gave the desired product (88) (0.073 g, 0.069 mmol, 34.5% yield). LC-MS (ESI): (exact mass: 1069.56) m/e═1070.9 [M+1]+ (100%).
