Reaction Steps

4-{4-[5-(3-Fluoro-5-iodo-phenylcarbamoyl)-pyridin-2-yl]-piperazin-1-yl}-benzoic acid ethyl ester was prepared from 6-chloro-N-(3-fluoro-5-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. The product was isolated after suspension in small volume of EtOAc filtration and a wash with CH3CN. HRMS m/z calcd for C25H24N4O3FI [M+H]+: 575.0950. Found: 575.0947.
