PROCEDURE

实验过程

To tert-butyl 3-(4-carbamoyl-3-fluorophenylamino)-2-(4-(hydroxymethyl)phenyl)-3-oxopropylcarbamate (E337-1) in pyridine was added was added EDC, DMAP, and 2,4-dimethylbenzoic acid, and the solution was stirred overnight at room temperature. The mixture was poured into NaHCO3(sat) and extracted with EtOAc. The organics were dried (MgSO4), filtered, and evaporated. Column chromatography (SiO2, 0-5% MeOH/CH2Cl2 gradient) gave pure 4-(3-(tert-butoxycarbonylamino)-1-(4-carbamoyl-3-fluorophenylamino)-1-oxopropan-2-yl)benzyl 2,4-dimethylbenzoate (E337-2).
