Procedure

Tetrabutyl ammonium fluoride solution (2.38 mL, 1M in THF) was added to a solution of 4-(5-{3-[3′-[5-(tert-butoxycarbonylamino-imino-methyl)-2-methylsulfanyl-thiophene-3-sulfonyl]-6-methyl-4-(2-trimethylsilanyl-ethoxycarbonylamino)-biphenyl-2-yl]-ureido}-pentyloxy)-benzoic acid (276 mg, 0.298 mmol, Example 283: step d) in THF (10 mL) over 2 days at 35° C. The solvents were removed in vacuo. The residue was diluted in EtOAc, washed with water and brine, and dried over magnesium sulfate. The solvents were removed in vacuo to afford the title compound as a brown solid (300 mg, quantitative). ESI-MS (m/z): Calcd. for C37H44N5O8S3: 782.2 (M+1); found: 781.8.
