Reaction Steps

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 methyl ester (25 mg, 0.06 mmol, Example 124: step a), 2-methyl phenyl boronic acid (33 mg, 0.25 mmol), Pd(PPh3)4 (14 mg, 0.01 mmol), aqueous Na2CO3 (2M, 400 μL, 0.5 mmol), ethanol (400 μL) and toluene (800 μL). The reaction was heated to 80° C. for 12 hours. The residue was dissolved into EtOAc and washed with brine. The organic layers were dried (MgSO4) and removal of the solvents in vacuo was followed by preparative SiO2 TLC purification (20% MeOH in DCM) that yielded the title compound (7.4 mg, 29%) as a white solid. ESI-MS (m/z): Calcd. for C19H18N2O4S3: 420.0 (M+1) found: 420.2.
