Versuchsvorschrift

To a solution of acetic hydrazide (2g, 27.0 mmol) in EtOH (5 mL) was added benzenesulfonic acid (4.7g, 29.7 mmol) in small portions. A white solid formed. A volume of Et2O (5 mL) was added to the mixture. The resulting solid was collected by filtration, washed with Et2O, and dried to give compound 11a. 1H NMR (D2O) δ 1.95 (s, 3H), 7.45 (m, 3H), 7.75 (d, 2H).
