실험 절차
A solution of 653 mg of Compound 5 obtained in the above step (1) as crystals in 3.2 ml of fuming nitric acid is stirred at 55° C. for 3 hours. The reaction mixture is chilled, poured onto ice water and shaken with chloroform. The extract is washed with water, aqueous disodium hydrogen phosphate and saturated saline in this order, dried over anhydrous magnesium sulfate and concentrated to remove the solvent. The resultant residue is washed with methanol to give 551 mg of the titled compound 6 as light yellow crystals.
