YieldReaction ConditionsOperation in experiment
79% With dmap; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In dichloromethane; at 40℃; for 12h; Bendamustine hydrochloride (Compound 5b) (454 mg, 1.10 mmol), EDCI (384, 2.00 mmol), DMAP (227 mg, 50%) and Compound 4 (492 mg, 1.00 mmol) were dissolved in 10 mL of dry CH2Cl2. The reaction was heated at 40 C for 12 h.After the reaction is completed, the solvent is evaporated under reduced pressure, and the crude material is purified by column chromatography.(mobile phase ethyl acetate: petroleum ether = 2:1-4:1) gave 656 mg of pale yellow solid.The yield was 79%.
