Procedure

Sodium hydride (60% in oil) (6 mg) was added to a DMF (1 ml) solution containing 3-bromo-5-(1H-pyrrol-3-yl)pyridine (28 mg), followed by stirring. Methyl iodide (9 μl) was added, followed by stirring at room temperature for 3 hours. The reaction solution was poured into water, followed by extraction with ethyl acetate. The resultant was washed with saturated saline and dried over anhydrous sodium sulfate. Then, the solvent was distilled away under reduced pressure, the obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=30:1 to 3:1), and a white solid of 3-bromo-5-(1-methyl-1H-pyrrol-3-yl)pyridine (18 mg) was thus obtained.
