Participants

Reaction Steps

N-phenyl-1,2-phenylenediamine (25 g, 0.136 mol) was dissolved in 100 ml N-methyl-2-pyrrolidinone (NMP) and o-anisoyl chloride (23.2 g, 0.136 mol) was then added to the solution at room temperature under nitrogen. The reaction mixture was stirred for 30 minutes at room temperature and then the temperature was increased to 220° C. for three hours during which time a white solid precipitated out of solution. After cooling, 150 ml of water was added to the reaction mixture and product was extracted with 300 ml of dichloromethane. The organic layer was washed with water and then dried with sodium sulfate. After removal of the solvents, the desired product o-(1-phenyl-2-benzimidazolyl) anisole was obtained.
