Reaction Steps

To a stirred solution of 5.0 g (0.023 mol) of benzenesulfonyl-acetic acid methyl ester in 10 mL of MeOH at RT, 3.50 g (0.070 mol, 3 eq) of hydrazine hydrate were added. After one hour, the solvent and the excess of hydrazine were removed under reduced pressure, yielding 4.90 g (quantitative) of benzenesulfonyl-acetic acid hydrazide as a colorless oil, MS: 232 (MNH4+).
