PROCEDURE
实验过程
Lithium hydroxide (53.8 μL, 0.215 mmol, 4N aqueous) was added to a solution of 6-{3-[3′-[5-(tert-butoxycarbonylamino-imino-methyl)-2-methylsulfanyl-thiophene-3-sulfonyl]-2-(4-methoxycarbonyl-butyrylamino)-6-methyl-biphenyl-4-yl]-ureido}-hexanoic acid ethyl ester (45.5 mg, 53.8 μmol, Example 278: step d) in MeOH/H2O (10 mL, 2:1) at 0° C. The reaction mixture was warmed to rt and stirred overnight. The solvents were removed in vacuo to afford the title compound as a yellow solid (50 mg, quantitative). ESI-MS (m/z): Calcd. for C36H45N5O10S3: 804.2 (M+1); found: 803.9.
