실험 절차

To a solution of 4-picoline (18.6 g, 0.2 mol) in toluene (100 mL), methyl iodide (56.8 g, 0.4 mol) was added dropwise at room temperature. After the addition, the mixture was stirred at room temperature for 5 hrs. The precipitate was collected by filtration, washed with toluene and dried under vacuum to give Compound 7 as an off-white solid (31.6 g, 67%). The structure of Compound 7 is given below:
