2-(2-(2-(5-bromo-1-(4-cyanonaphthalen-1-yl)-1H-imidazol-2-ylthio)-2,2-difluoroacetamido)acetamido)acetic acid is prepared via either of the two routes shown below. In the first, 2-(2-(5-bromo-1-(4-cyanonaphthalen-1-yl)-1H-imidazol-2-ylthio)-2,2-difluoroacetamido)acetic acid (see eg 14) is coupled with glycine ethyl ester and then hydrolyzed to the acid. In the second, (see eg 10), 2-(5-bromo-1-(4-cyanonaphthalen-1-yl)-1H-imidazol-2-ylthio)-2,2-difluoroacetic acid is coupled with NH2-Gly-Gly-OEt, which is then hydrolyzed to the acid.
