실험 절차

A solution of 3.8 g (55 mol) of hydroxylamine hydrochloride in 100 ml of water was neutralized by the addition of 55 ml (55 mmol) of 1.0 N sodium hydroxide. To this was added a suspension of 16.5 g (50 mmol) of 7-(3 oxocyclopentyl)-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxoquinoline acid in a mixture of 150 ml of ethanol and 50 ml (50 mmol) of 1.0 N sodium hydroxide. The reaction mixture was heated at 60° for 4 hours and then at room temperature overnight. The alcohol was removed in vacuo and the aqueous was acidified to pH 2.0 with 6.0 M hydrochloric acid. The solid was removed by filtration, washed with water, and dried in vacuo to give 16.1 g of the title compound.
