Reaction Steps

Ethyl[2-[2-(5-cyano-2-hydroxybenzenesulfonylamino)ethyl]-5-isopropylphenoxy]acetate (0.266 g) was dissolved in 5 mL of ethanol. To the solution was added 0.087 mL of hydrazine monohydrate at room temperature, and the mixture was refluxed for 1 hour. The solvent was removed under reduced pressure to give 0.258 g of 5-cyano-N-[2-(2-hydrazinocarbonylmethoxy-4-isopropylphenyl)ethyl]-2-hydroxybenzenesulfonamide.
