実験手順

To a suspension of 4-Phenyl-thiazole-2-carboxylic acid (100 mg, 0.4 mmol) and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (0.44 mmol) in DMF (4 mL) at 25° C. was added phenylalanine methyl ester (72 mg, 0.4 mmol), the resulting mixture was stirring at 25° C. for overnight and concentrated in vacuo, and the residue was dissolved in CH2Cl2 (20 mL) was washed with 5% NaHCO3, dried with MgSO4 and concentrated in vacuo. The residue was purified by HPLC. The product was obtained 92 mg (61%) as white solid.
