실험 절차

The compound (100 mg) obtained in Step 2 of Example 21 was dissolved in 6N hydrochloric acid (0.5 mL) at room temperature and stirred at the same temperature for five hours. To the mixture was added water (3 mL) and adjusted to pH 9 to 10 by potassium carbonate, and the aqueous layer was washed with ethyl acetate. Insoluble matter of the aqueous layer was removed by filtration and the filtrate was adjusted to pH 3 with 6N hydrochloric acid. The precipitate was collected by filtration and dried to obtain the titled compound (71 mg) as crystals. The physical data of the obtained compound accord with those of the compound of Example 29.
