Participants

Reaction Steps

To a stirred solution of the crude (R)-1-(1-(2,4-dichlorophenyl)ethyl)-6-(piperazin-1-yl)-1H-benzo[d]imidazole (0.10 g, 0.27 mmol) and (R)-1-(t-butoxycarbonyl)pyrrolidine-2-carboxylic acid (0.064 g, 0.32 mmol) in dichloromethane (2 mL) was added HATU (0.12 g, 0.32 mmol) and triethylamine (Et3N, 0.2 mL, 1.4 mmol). The reaction mixture was stirred at room temperature for 2 h, and diluted with ethyl acetate. The mixture was washed with saturated aqueous sodium bicarbonate and brine. The organic layer was dried (Na2SO4), filtered, and concentrated in vacuo. The crude product was purified by flash chromatography (SiO2, 10% methanol in dichloromethane) to afford the desired product (0.11 g, 0.19 mmol, 71% for 2 steps).
