Reaction Steps

The reaction was conducted following the procedure for Example 156: step a, using 4-(5-bromo-6-chloro-pyridine-3-sulfonyl)-5-methylsulfanyl-thiophene-2-carboxylic acid methyl ester (0.050 g, 0.113 mmol), (Example 2: step c), 3-aminomethyl-6-trifluoromethyl pyridine (0.026 g, 0.146 mmol), diisopropylethylamine (0.073 g, 0.565 mmol), THF [0.5 mL], DMF [0.5 mL]. Chromatography of the residue (25%–50% EtOAc/Hx) yielded the title compound. ESI-MS (m/z): Calcd. For C19H15BrN3O4S3: 583.44 (M+H); found 582.0, 583.9.
