Procedure

Add acetic acid (1.00 mL, 17.45 mmol) and phenyl hydrazine (1.98 mL, 20.00 mmol) to a solution of 2-butanone (2.15 mL, 24.00 mmol) in ethanol (90 mL) at room temperature. Stir the reaction for 1 hr., then remove the solvents in vacuo to give N-[1-methyl-prop-(E)-ylidene]-N′-phenyl-hydrazine as a crude orange oil (3.21 g, 99%). MS (ES): m/z=163 [M+H]+.
