실험 절차

A mixture of compound 13 (1.08 g) in trifluoroacetic acid (17 mL) was stirred at 60° C. for 5 hrs. The solution was then cooled down at 0° C., water was added, and the mixture was extracted with EtOAc. Organics were washed with saturated NaHCO3, dried over Na2SO4, filtered, and concentrated under reduced pressure. The crude material was purified by chromatography on silica gel (DCM/MeOH) to yield compound 14 as a white powder in 97% yield. MS (ESI, EI+) m/z=482 (MH+).
