Reaction Steps

({4-[4′-(3-Hexyl-thioureido)-2′-methyl-biphenyl-3-sulfonyl]-5-methylsulfanyl-thiophen-2-yl}-imino-methyl)-carbamic acid tert-butyl ester (33 mg, 0.14 mmol. Example 136: step a) was dissolved into ammonia in methanol (2.0 M, 4 mL). To this was added mercury (II) oxide (33.9 mg, 0.16 mmol) and the reaction stirred at RT for 2 hours. Additional mercury (II) oxide (154 mg, 0.08 mmol) was added and the reaction was heated to 40° C. overnight. The reaction was filtered with 0.2 μM disk and washed with EtOAc followed by removal of solvents in vacuo that yielded the title compound which was used without further purification (30 mg). ESI-MS (m/z): Calcd. for C31H41N5O4S3: 644.2 (M+1); found: 644.1.
