Reaction Steps

To a solution of 0.21 g of ethyl N-[2-[2-(5-cyano-2-methoxybenzenesulfonylamino)ethyl]-5-isopropylphenyl]oxalamate in 3 mL of N,N-dimethylformamide was added 56 mg of lithium chloride, and the mixture was stirred at 140° C. for 4 hours. To the reaction mixture was added 1 mol/L hydrochloric acid, and the mixture was extracted with ethyl acetate. After the organic layer was dried over anhydrous sodium sulfate, the solvent was removed under reduced pressure to give 0.198 g of N-[2-[2-(5-cyano-2-hydroxybenzenesulfonylamino)ethyl]-5-isopropylphenyl]oxalamic acid.
