Procedure

methyl 7-{[(dimethylamino)sulfonyl]amino}-5-oxo-5H-benzo[4,5]cyclohepta[1,2-b]pyridine-3-carboxylate (17 mg, 0.044 mmol) was dissolved in 1 mL of THF and 1 mL of 1 M aqueous sodium hydroxide. After 2 h the mixture was quenched by the addition of 1.1 mL of 1M HCl and the organics were removed in vacuo. The material was freeze dried to afford 7-{[(dimethylamino)sulfonyl]amino}-5-oxo-5H-benzo[4,5]cyclohepta[1,2-b]pyridine-3-carboxylic acid.
