Reaction Conditions

Temperature	60 °C

Reaction Steps

To the compound (3.00 g) obtained in Example 9, 4N hydrogen chloride/dioxane (15 mL) was added. The reaction solution was stirred at 60° C. for 15 hours. The reaction solution was concentrated under reduced pressure. The residue was dissolved in methanol (20 mL) and a carbonate resin (trade name: MP-Carbonate, manufactured by Argonaut Co., product number: 800267, 10 g) was added, followed by stirring at room temperature for 3 hours. After the resin was removed by filtration, the filtrate was concentrated under reduced pressure. The title compound was obtained without purifying the residue.
