97% | With benzotriazol-1-yloxyl-tris-(pyrrolidino)-phosphonium hexafluorophosphate; triethylamine; In dichloromethane; acetonitrile; at 20℃; | General procedure: A mixture of 1 mmol (1 equiv.) of carboxylic acids, 1.4 mmol (1.4 equiv.) of amine, 552 mg (1.8 equiv.) of PyBOP and 2 mL of triethylamine was stirred overnight at room temperature in 40 ml of a 1:1 mixture of CH2Cl2 and CH3CN. After solvent evaporation, the crude product was purified by column chromatography on silica (CHCl3:CH3CH2OH = 9:1) resulting in yellow thick oil that slowly crystallized. |

With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; triethylamine; In dichloromethane; at 20℃; for 6h; | General procedure: To a solution of 2-(3,4-dimethoxyphenyl)acetic acid 5 (0.77g, 3.93mmol) in CH2Cl2, 2-thiophene ethylamine (0.50g, 3.93mmol), EDC-HCl (N-ethyl-N?-(3-dimethylaminopropyl)carbodiimide hydrochloride, 1.13g, 5.90mmol), HOBt (hydroxybenzotriazole, 0.69g, 5.11mmol) and triethylamine (0.40g, 3.93mmol) were added. The mixture was stirred for 6hat room temperature, washed with water and brine, dried over Na2SO4, filtered, and concentrated. The residue was recrystallized from ethyl acetate to afford 6 (1.6g, 86percent) as a white solid. |
