PROCEDURE

实验过程

To 3-(tert-butoxycarbonylamino)-2-(4-((triisopropylsilyloxy)methyl)phenyl)propanoic acid in pyridine was added EDC, DMAP, and 4-amino-2-fluorobenzamide (E336), and the solution was stirred overnight at room temperature. The mixture was poured into NaHCO3(sat) and extracted with EtOAc. The extracts were dried (MgSO4), filtered, and evaporated. Column chromatography (SiO2, 0-6% MeOH/CH2Cl2 gradient) gave pure tert-butyl 3-(4-carbamoyl-3-fluorophenylamino)-3-oxo-2-(4-((triisopropylsilyloxy)methyl)phenyl)propylcarbamate (E337).
