Procedure

{[4-(2′-Amino-6′-methyl-biphenyl-3-sulfonyl)-5-methylsulfanyl-thiophen-2-yl]-imino-methyl}-carbamic acid tert-butyl ester (38.5 mg, 0.07 mmol, Example 25: step c) and 3-chlorocaxbonyl-propionic acid ethyl ester (13 μL, 0.09 mmol) were dissolved into THF (1 mL) and heated to 50° C. for one hour. The reaction was dissolved into EtOAc and washed with brine. The combined organic layers were dried, (MgSO4) and the solvents were removed in vacuo. Purification by preparative TLC (30% EtOAc/hexanes) yielded the title compound. ESI-MS (m/z): Calcd. for C30H35N3O7S3: 646.2 (M+1); found: 645.8.
