A Wolff–Kishner reaction that does not require hydrazine has been developed. The reaction sequence has two steps; formation of a carbomethoxyhydrazone from methyl hydrazinocarboxylate and acetophenone, then decomposition of this intermediate by treatment with potassium hydroxide in triethylene glycol. Purification is by filtration through a plug of silica encased in the barrel of a plastic syringe. The reaction sequence can be completed within a day-long laboratory class (8 hours).
