1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → (3,4-Difluorophenyl)-[1-(3,4-difluorophenyl)-1H-benzoimidazol-2-yl]amine

Participants

Reaction Steps

The title compound was prepared by Procedure G from N-(3,4-difluorophenyl)-benzene-1,2-diamine (Scheme 5), 3,4-difluorophenyl isothiocyanate and, in the last step, 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide. The reaction mixture was evaporated to dryness and the remaining crude product purified by preparative LCMS to give the title compound as the free base (solid, mp 115-117° C.). MS(ES+) m/z 358 ([M+1]+, 100).
