Versuchsvorschrift
The compound (6.27 g, 20.0 mmol) obtained in step A was dissolved in ethyl acetate, 4N hydrochloric acid-ethyl acetate solution (25 ml, 100 mmol) was added at room temperature with stirring, and the mixture was stirred at the same temperature overnight. The precipitated solid was filtered, washed with ethyl acetate, and dried under reduced pressure to give the title compound (4.65 g, yield 93%) as a colorless solid.
