Pyridine → HCID 3267779, compound

To a solution of 4-{2-{[tert-butyl)amino]sulfonyl}phenyl}benzoic acid (167 mg, 0.5 mmol) in dichloromethane (5 ml) was added oxalyl chloride (0.09 ml, 1 mmol) and a few drops of dimethylformamide. The mixture was stirred at r.t. for 2 hrs. After the evaporation of the solvent, the residue was dissolved in dichloromethane (5 ml). The compound of (2-amino-5-chlorophenyl)-N-(5-chloro(2-pyridyl))carboxamide (0.17 g, 0.6 mmol) and pyridine (0.122 ml, 1.5 mmol) were added to the solution. The mixture was stirred at r.t. overnight. The solvent was evaporated to give (2-{[4-(2-{[tert-butyl)amino]sulfonyl}phenyl)phenyl]-carbonylamino}-5-chlorophenyl)-N-(5-chloro(2-pyridyl))carboxamide. MS found for C29H26Cl2N4O4S M+=597, (M+2)+=599. Step 2: The mixture of the compound of (2-{[4-(2-{[(tert-butyl)amino]sulfonyl}phenyl)phenyl]carbonylamino}-5-chlorophenyl)-N-(5-chloro(2-pyridyl))carboxamide example 12 (0.5 mmol) in trifluoroacetic acid (5 ml) was stirred at r.t. for 5 hrs. After the evaporation of solvent, the crude residue was purified by RP-HPLC to give N-(5-chloro(2-pyridyl))(5-chloro-2-{[4-(2-sulfamoylphenyl)-phenyl]carbonylamino}phenyl)-carboxamide as a white powder (68 mg, 25%). MS found for C25H18Cl2N4O4S
