반응 단계

Intermediate 14F (825 mg, 1.67 mmol) was dried azeotropically with toluene (2×). The residue was taken up in 15% TFA in CH2Cl2 (10 mL) and stirred at rt for 5 h. Toluene (10 mL) was added and solvent was removed under vacuum. The product was purified by reverse phase HPLC (Phenoenex Luna 30×100 mm S5 C18, 10 min. grad, 25 mL/min, 20-100% B solvent, A=10% MeOH/water+0.1% TFA, B=90% MeOH/Water+0.1% TFA, 4 injections). Solvent was reduced to 10% volume and the product was then extracted into EtOAc, washed with sat. aqueous NaHCO3, dried over MgSO4 and filtered. Solvents were removed to provide the title compound (371 mg): MS (ES) m/z 394.53 [M+H]+
