Reaction Steps

To a four necked flask equipped with a thermometer, reflux condenser and stirrer, 400 g of N,N-dimethylformamide (DMF), 40 g of toluene, 80 g (0.47 mol) of p-phenylphenol, 86.9 g (0.517 mol) of m-dinitrobenzene, and 35.9 g (0.26 mol) of potassium carbonate were charged. The mixture was heated to 140° C. with stirring and aged at 140° C. for 15 hours. After finishing the reaction, the reaction mixture was cooled to 100° C. and filtered to remove inorganic salts. The filtrate was incorporated with 300 g of water and cooled to room temperature to crystallize the desired product. The precipitated crystals were filtered and recrystallized from a mixture of 380 g of DMF and 100 g of water to obtain 96 g (70% yield) of 4-(3-nitrophenoxy)-1,1'-biphenyl (NPBP).
