실험 절차

To a solution of methyl 11-cyclohexyl-5-oxa-6a-azabenzo[a]fluorene-8-carboxylate (40 mg, 0.11 mmol) in tetrahydrofuran (1 ml) and methanol (1 ml) was added 4N aqueous sodium hydroxide solution (1 ml), and the mixture was stirred at 60° C. for 3 hr. 1N Hydrochloric acid was added to the reaction mixture, and the precipitated solid was collected by filtration, washed with hexane and dried in vacuo to give 11-cyclohexyl-5-oxa-6a-azabenzo[a]fluorene-8-carboxylic acid (26 mg, yield 68.4%).
