실험 절차
A mixture of 1.0 g of 4-bromoimidazole, 1.3 g of 3-chloro-2-(methanesulfonyl)pyridine, 2.7 g of cesium carbonate and 10 ml of N,N-dimethylformamide was stirred at 100° C. for 6 hours. The reaction mixture was allowed to cool to room temperature, and water was poured into the mixture. A deposited precipitate was collected by filtration to obtain 1.7 g of 2-(4-bromo-1H-imidazol-1-yl)-3-chloropyridine of the formula:
