Reaction Steps

A tetrahydrofuran solution of 3.27 g of 3-methyl-2-nitrocinnamoyl chloride was dropped into a tetrahydrofuran solution of 3.41 g of o-phenylenediamine. The obtained mixture was stirred at room temperature for one hour to complete a reaction. Thereafter, the obtained solution was concentrated and extracted with ethyl acetate. The residue was heated in acetic acid at 100° C. for 2 hours to give 3.67 g of 3-[2-(1H-benzimidazol-2-yl)vinyl]-2-nitrotoluene.
