Procedure
4-{4-[5-(3-Chloro-4-iodo-phenylcarbamoyl)-pyridin-2-yl]-piperazin-1-yl}-benzoic acid ethyl ester was prepared from 6-chloro-N-(3-chloro-4-Iodo-phenyl)-nicotinamide and 4-(piperazin-1-yl)-benzoic acid ethyl ester following a method similar to the one described in the synthesis of 4-{4-[5-(3-iodo-4-methyl-phenylcarbamoyl)-pyridin-2-yl]-piperazin-1-yl}-benzoic acid ethyl ester above. HRMS m/z calcd for C25H24N4O3ClI [M+H]+: 591.0655. Found: 591.0657.
