실험 절차

{[4-(2′-Amino-4′-chloro-6′-methyl-biphenyl-3-sulfonyl)-5-methylsulfanyl-thiophen-2-yl]-imino-methyl}-carbamic acid tert-butyl ester (120 mg, 0.22 mmol, Example 135, e) and Et3N (0.91 μL, 0.65 mmol) were dissolved into DCM (4 mL). To this was added (4-Methanesulfonyl-butyryl chloride (0.144 M, 3.1 mL, 0.44 mmol, Example 209: a) and the reaction was stirred at RT overnight. The solvents were removed in vacuo followed by purification by flash column chromatography (20% EtOAc/hexanes) that yielded the title compound as an orange solid (124 mg, 81%). ESI-MS (m/z): Calcd. for C29H34ClN3O7S4: 700.1 (M+1) found: 700.1.
