The resulting solution was heated to reflux for 16 hrs in an oil bath. The reaction mixture was cooled and quenched by the addition of 100 mL of water. The resulting solution was extracted with 5x200 mL of ethyl acetate. The organic layers were combined, washed with 3x200 mL of brine, dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column and eluted with ethyl acetate/petroleum ether (1: 1). This resulted in 5 g (73percent) of 2-chloro-4-(pyridin-3-yl)pyrimidine as a yellow solid.

The mixture was stirred at reflux for 14 h under N2 atmosphere. The reaction mixture was cooled to room temperature and filtrated. The filtrate was diluted with H2O (100 mL) and then extracted with EtOAc, and the organic layer was dried over anhydrous Na2SO4, After filtration, the filtrate was evaporation and purified by chromatography (petroleum ether/ EtOAc, 5:1) to give the product as oil (700 mg, 73 percent).
