2-Benzyl-5-[1,3]dioxolan-2-yl-pyridine (7.3 g, 30 mmol) described in Manufacturing Example 210-1-3 and 2 N hydrochloric acid (100 mL) were stirred for 15 minutes at 100° C. The reaction solution was cooled to room temperature and partitioned into ethyl acetate and a 5 N sodium hydroxide solution (40 mL). The organic layer was separated, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (4.7 g, 79%).
