실험 절차

To a solution of N-[2-bromo-4-[[[(3-hydroxyphenyl)methyl]amino]carbonyl]benzoyl]-3-(thiophene-2-carbonyl)amino-L-alanine methyl ester (Example 306; 195 mg, 0.348 mmol) in methanol (2 mL) at 25° C. was added 1 N NaOH (350 μL, 0.348 mmol). The reaction mixture was stirred for 24 h and TLC (10% methanol in dichloromethane) revealed that starting material was still present. 1 N NaOH (350 μL) was added at room temperature and the reaction was stirred for 24 h. The solvents were evaporated under reduced pressure, the residue was placed under vacuum for 1 h, and then purified by HPLC (gradient of acetonitrile, water, 0.075% TFA). The pure fractions were combined, concentrated under vacuum and then freeze dried for 24 h to yield N-[2-bromo-4-[[[(3-hydroxyphenyl)methyl]amino]carbonyl]benzoyl]-3-(thiophene-2-carbonyl)amino-L-alanine (144 mg, 76%) as a white solid.
