Reaction Steps

A mixture of 4-chloro-8-(2,6-dichlorobenzoylamino)-3-ethoxycarbonylquinoline (297 mg) and hydrazine monohydrate (175 mg) in ethanol (3 ml) was refluxed for 1 hour. To the mixture was added ice-water, and the resulting precipitate was collected by filtration and washed with water to give 6-(2,6-dichlorobenzoylamino)-2,3-dihydro-1H-pyrazolo[4,3-c]-quinolin-3-one (250 mg).
