Used Chemicals


1-(2-methoxyphenyl)piperazine (500 mg, 2.60 mmol) was dissolved in DMF (15 mL). To this solution was added N-benzyloxycarbonyl-L-phenylalanine (770 mg, 2.60 mmol) and HOBt·H2O (414 mg, 2.71 mmol). The reaction mixture was cooled to 0 °C, then EDC·HCl (515 mg, 2.71 mmol) was added. Reaction was allowed to warm to room temperature, then stirred for 20 h at room temperature. Complete of the reaction was confirmed by TLC. Reaction was quenched by adding H2O (20 mL). Reaction mixture was extracted by EtOAc (30 mL). Organic phase was washed with H2O (20 mL, twice) and brine (20 mL), dried over Na2SO4, concentrated under reduced pressure to afford the crude product (1.2 g) as pale yellow oil. The crude product was purified by column chromatography on silica gel (hexane : ethyl acetate = 40 : 60) to afford the product 1 as a white powder (1.10 g, 2.32 mmol, 90%).

Experimenter's Comments

The reaction mixture was monitored by TLC (hexane / ethyl acetate = 4 : 6, Rf = 0.40)

Analytical Data(Compound 1)

Formation of Peptide Bonds Using EDC·HCl /HOBt

Typical Procedure: To a solution of Boc-ΔTyr(Cl2Bzl)-OH (307 mg, 0.7 mmol), glycinamide hydrochloride (77.4 mg, 0.7 mmol) and Et3N (0.1 mL, 0.7 mmol) in DMF (7 mL) is added EDC·HCl (148 mg. 0.77 mmol) and HOBt (129 mg, 0.84 mmol) at -10°C. The reaction mixture is stirred for 2 h at 0°C. and overnight at room temperature. After the solution is evaporated, the residual is dissolved in EtOAc. The solution is washed with 4% NaHCO3, 10% citric acid and water. The solution is dried and evaporated. The purification is carried out by silica gel column chromatography to give Boc-ΔTyr(Cl2Bzl)-Gly-NH2 (317 mg, 85% yield).

  • Application
    Water-soluble Condensation Reagent

    Typical Procedure: To a 50 mL round bottom flask equipped with a magnetic stir bar and septum is added 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride 2.54 g (13.3 mmol), 4-dimethylaminopyridine 1.62 g (13.3 mmol), carboxylic acid 1.02 g (2.46 mmol), alcohol 0.96 g (3.98 mmol) and CHCl3 (15 mL), and the reaction mixture is stirred at room temperature for 2.5 days. Acetic acid (0.5 mL) is added and the reaction mixture is stirred for 10 min to convert excess alcohol to a more easily separable acetate. The mixture is washed with saturated aqueous NH4Cl solution, diluted with Et2O, and the layers are dried, filtered and concentrated under reduced pressure. The crude material is chromatographed by silica gel column chromatography (hexane:ethyl acetate = 9:1) to give the desired product 1.25 g (1.96 mmol, 80%).
