The mixture was stirred in a preheated oil bath at 125 C for 12 h. After cooling the mixture to the room temperature, 5 mL water was added and the product was extracted by ethyl acetate (10 mL\u00a1\u00c13). The combined organic layer was washed by brine (15 mL), dried over anhydrous MgSO4, and evaporated under the reduced pressure. Further purification by silica gel column chromatography (6:1 petroleum ether\/ethyl acetate) give the 1-phenyl-1H-imidazole.<\/p>\n<p>The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking.
