Procedure

An aqueous concentrated hydrochloric acid solution (36%, 760 μL, 8.5 mmol) was added at room temperature to a solution of the compound (3.07 g, 5.8 mmol) obtained in Example 3 in 2-propanol (20 mL), and the solution was stirred at room temperature for 15.5 hours. The precipitate was collected by filtration, washed with 2-propanol (2 mL×2), and dried under reduced pressure to obtain the title compound (2.26 g, 72%) as a white powder.
