Procedure

{[4-(6′-Amino-2′-methyl-biphenyl-3-sulfonyl)-5-methylsulfanyl-thiophen-2-yl]-imino-methyl}-carbamic acid tert-butyl ester (0.100 g, 0.204 mmol), (Example 25: step c), 4-nitrophenyl chloroformate (0.041 g, 0.204 mmol), pyridine (0.018 g, 0.224 mmol), DCM [3 mL] were added to a flask containing a stirbar. This solution was stirred at room temperature for 2.5 hours. To this solution was added (5-Amino-pentyl)-phosphonic acid diethyl ester (0.136 g, 0.611 mmol) and Triethylamine (0.062 g, 0.611 mmol). Solution was stirred at room temperature for 18 hours. Reaction was concentrated in vacuo followed by chromatography (50%–100% EtOAc/Hx) to yield title compound (0.138 g, 88%). ESI-MS (m/z): Calcd. for C34H47N4O8PS3: 767.93 (M+H); found 667.1.
