Reaction Steps

2-Mesitylbenzimidazole was synthesized by dissolving 1.5 g 1,2-phenylene diamine (14 mmol) in 40 g of PPA at 120° C. To this solution, 2.1 g of 2,4,6-trimethylbenzoic acid (13 mmol) was added and the temperature was increased to 150° C. After 16 h the solution was cooled to 60° C. and poured into water forming an off-white precipitate. The precipitate was separated by filtration and washed thoroughly with water, yielding 2.6 g of light brown powder (85% yield).
