Procedure
(4-Iodo-5-methyl-pyridin-3-yl)-carbamic acid tert-butyl ester (106 mg, 0.32 mmol, Example 139: step b), {[4-(3-Boranyl-dihydroxy-benzenesulfonyl)-5-methylsulfanyl-thiophen-2-yl]-imino-methyl}-carbamic acid tert-butyl ester (145 mg, 0.32 mmol, Example 140: step a) and Pd(PPh3)4 (74 mg, 0.06 mmol) were combined in aqueous Na2CO3 (2M, 1.2 mL), ethanol (1.2 mL) and toluene (2.4 mL) and was heated to 80° C. overnight. The reaction mixture was dissolved into EtOAc and washed with brine. The organic layers were dried MgSO4) and solvents were removed in vacuo. Purification by flash column chromatography (40% EtOAc/hexanes) afforded the title compound. ESI-MS (m/z): Calcd. for C28H34N4O6S3: 619.2 (M+1); found: 618.8.
