Procedure
854 mg (1.62 mmol) of the compound obtained in step 1 described above was dissolved in 20 ml of 1,4-dioxane. 2 ml of 4 N hydrochloric acid/1,4-dioxane was added to the obtained solution under cooling with ice, and they were stirred at room temperature for 2.5 hours. The reaction mixture was cooled with ice, 5 ml of 4 N hydrochloric acid/1,4-dioxane was added thereto, and they were stirred at room temperature for 2 hours. 2.5 ml of 4 N hydrochloric acid/1,4-dioxane was added to the reaction mixture under cooling with ice. After stirring at room temperature for 1 hour, 7.5 ml of 4 N hydrochloric acid/1,4-dioxane was added to the reaction mixture, and they were stirred at room temperature for 2 hours. The solvent was concentrated under reduced pressure. Diethyl ether was added to the residue, and crystals thus formed were taken by the filtration to obtain the title compound.
