실험 절차
In a 100 ml round bottom flask equipped with stir bar added Methyl-3-bromo-5-(3-pyridyl)benzoate (1.16 g, 3.96 mmol), methanol (15 ml) and sodium hydroxide (5.94 ml, 5.94 mmol, 1N aqueous). Stirred the resulting mixture at 50° C. for 2 h. The reaction mixture was cooled to room temperature, concentrated in-vacuo and the residue was dissolved in methanol (20 ml). To this mixture added hydrochloric acid (1N diethyl ether) dropwise and stirred at room temperature for 10 min. The reaction mixture was concentrated in-vacuo and the residue was triturated with diethyl ether to provide the crude hydrochloride salt of title compound (1.50 g) as a white solid.
