75.4% | In the water bath, N-t-butoxycarbonyl-Nim-triphenylmethyl-histidine (22 mmol, 7.6 g) N,N'-dicyclohexylcarbodiimide (4. 4 mmol, 0.91 g), 4-dimethylamino-pyridine (2. 2 mmol, 0.3 g) And stirred with anhydrous dichloromethane (30 ml). Followed by the addition of L-ornidazole (26mmol, 5.7g) and stirred overnight at room temperature. The insoluble matter was removed by filtration, and the filtrate was evaporated to dryness. The ether was added to the residue and the insoluble impurities in the solution were removed by filtration. The filtrate was concentrated and the column was rapidly passed through ether and the product fractions were collected. The product was concentrated under reduced pressure. The resulting product was added directly to 4MHC1 / dioxane Ring solution (10ml), stirring at room temperature 1h. The solvent was distilled off under reduced pressure and concentrated to dryness. The residue was purified by HPLC (TFA) system to give product 4.3 g; compound 8 yield 75. 4percent. |
