ConditionsYieldWith benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; diisopropylamine In dichloromethane at 0 - 20℃; for 6h;Experimental Procedure2.2-1.3 Step 3: Preparation of Compound II-1eCompound II-1d (305 mg, 830 umol)II-1a 8- (Fluorenylmethoxycarbonyl-amino) -3,6-dioxaotanoic acid (478 mg, 1.24 mmol)Dichloromethane (20 mL)After melting in, At 0 to room temperatureI- (3-dimethylaminopropyl) -3-ethylcarbodiimide hydrochloride (318 mg, 1.66 mmol), hydroxybenzotriazole (224 mg, 1.66 mmol) and diisopropylamine (423 μl, 2.49 mmol) Was added. The reaction mixture was stirred at room temperature for 6 hours. After completion of the reaction and extracted with distilled water and brine, the organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The concentrated residue was purified by silica gel column chromatography (dichloromethane: methanol = 10: 1 volume ratio) to give the title compound II-1e (570 mg, 92%) as a yellow oil.92%
