Reaction Steps
12.69 g (46 mmole) of 2-(4-bromophenyl)-1H-benzo[d]imidazole, 3.17 g of K2CO3 (23 mmole), 120 ml of DMF, and 11.6 ml of dimethyl carbonate (138 mmole) were mixed together and heat to reflux. The reaction was completed in 3.5 hours. The reaction mixture was cooled to 3° C., and 250 ml of ice cold water was slowly added, The precipitated was filtered, and wash with 3*50 ml of water, this wet cake was dried under vacuum to get 9.96 g of product (yield=75.44%).
