HCID 20800257N-[(5-chloro(2-thienyl))sulfonyl]-N'-[4-(5-chloro-1,3-dioxobenzo [c]azolidin-2-yl)-3-methylphenyl]ethane-1,2-diamide収率 44%

実験手順

A 200 mg (1.0 mmol) of 5-chlorothiophenesulfonamide was slurried in 0.5 mL of oxalyl chloride and refluxed for 6 h. The solvent was removed in vacuo and 36 mg of the resulting solid was dissolved in 240 μL acetonitrile and treated with 40 mg (0.14 mmol) 2-(4-amino-2-methylphenyl)-5-chlorobenzo[c]azoline-1,3-dione. After stirring for 1 h, the solvent was removed and the residue was purified by RP-HPLC to give 33 mg (44%) of the titled compound. ES-MS (M+H)+=538(2Cl).
