Reaction Steps

4-{4-[5-(4-tert-Butyl-pyrimidin-2-ylcarbamoyl)-pyridin-2-yl]-piperazin-1-yl}-benzoic acid ethyl ester was prepared from N-(4-tert-butyl-pyrimidin-2-yl)-6-chloro-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 silica gel column with 30-100% EtOAc in hexanes. HRMS m/z calcd for C27H32N6O3 [M+H]+: 489.2609. Found: 489.2609.
