PROCEDURE
实验过程
A 25 mL round-bottomed flask was charged with 2-[5-bromo-4-(4-cyclopropyl-naphthalen-1-yl)-4H-[1,2,4]triazol-3-ylsulfanyl]-N-(2-chloro-4-sulfamoylphenyl)acetamide (50 mg, 0.085 mmol), EDC (35 mg, 0.18 mmol), Boc-Lys(Boc)-OH DCHA (47 mg, 0.09 mmol) in the mixture of 5 mL THF and 5 mL methylene chloride. To the mixture was added DMAP (16 mg, 0.13 mmol) in one portion. The reaction mixture was stirred at RT for 14 h. The solvents were evaporated under reduced pressure yielding thick oily residue. The residue was dissolved in 5 mL 4.0 M HCl in dioxane. The reaction was stirred at RT for 14 h. The solvent was evaporated under reduced pressure yielding thick oily residue. The residue was washed successively with 10 mL methylene chloride and 10 mL ether yielding the title compound as a light yellow solid (44 mg, 65%).
