실험 절차
A solution of HCl in dioxane (4.65 mL, 0.8 M, 3.72 mmol) was added to a solution of 2-(4-(pyridin-2-yl)but-3-ynyl)benzo[d]oxazole (923 mg, 3.72 mmol) in dioxane (50 mL). The resulting suspension was cooled at 0° C. for 1 hour and was filtered. The precipitate was washed twice with dioxane and dried under vacuum to yield 2-(4-(pyridin-2-yl)but-3-ynyl)benzo[d]oxazole hydrochloride (830 mg, 2.91 mmol, 78%) as a white solid (M.P.=143.5-145° C.).
