Procedure

The procedure as in Example 1: step c was followed using 4-(6-amino-5-bromo-pyridine-3-sulfonyl)-5-methylsulfanyl-thiophene-2-carboxylic acid amide (25 mg, 0.06 mmol, Example 120: step a), o-tolyl phenyl boronic acid (33 mg, 0.25 mmol), Pd(PPh3)4 (14 mg, 0.01 mmol), aqueous Na2CO3 (2M, 0.4 mL), ethanol (0.4 mL) and toluene (0.8 mL). Purification by preparative SiO2 chromatography (25% EtOAc in hexanes) of the residue yielded the title compound (7.4 mg, 32%) as a brown solid. ESI-MS (m/z): Calcd. for C18H17N3O3S3: 420.0 (M+H); found: 420.2.
