Hydrazine hydrate (1:1) → 6-(2-Chlorophenyl)-3-methoxymethyl-4,5,6,7-tetrahydroindazol-4-one

Participants

Reaction Steps

A solution of 5-(2-chlorophenyl)-2-(1-hydroxy-2-methoxyethylidene)cyclohexane-1,3-dione (0.4 g) and hydrazine hydrate (0.072 g) in ethanol (15 ml) was refluxed for 1 hour. Under reduced pressure, the solvent was evaporated, and the residue was purified with silica gel column chromatography to give 6-(2-chlorophenyl)-3-methoxymethyl-4,5,6,7-tetrahydroindazol-4-one (0.1 g) as oil.
