실험 절차

To a solution of Intermediate 1 in CH2Cl2 was added triethyl amine and ethylchloroformate at 0° C. The mixture was warmed to ambient temperature and stirred for 10 min. The reaction was complete by LCMS analysis and concentrated in vacuo to yield crude residue. To the crude residue was added CH2Cl2 and cyclopropyl amine, followed by stirring for ½ hr. LCMS indicated the reaction was complete. The reaction was diluted with CH2Cl2, washed with 0.5 N NaOH, H2O, brine, dried over MgSO4, and concentrated in vacuo. The crude residue was purified via silica gel chromatography (EtOAc/CH2Cl2/MeOH).
