Reaction Steps

4-{4-[5-(3-Iodo-4-methyl-phenylcarbamoyl)-pyridin-2-yl]-piperazin-1-yl}-2,2-dimethyl-4-oxo-butyric acid was prepared from 4-[5-(3-iodo-4-methyl-phenylcarbamoyl)-pyridin-2-yl]-piperazine-1-carboxylic acid tert-butyl ester and 2,2-dimethysuccinic anhydride following a procedure similar to the one described in the synthesis of 4-{4-[5-(4-iodo-3-methyl-phenylcarbamoyl)-pyridin-2-yl]-piperazin-1-yl}-dimethyl-4-oxo-butyric acid above. HRMS m/z calcd for C23H27N4O4I [M+H]+: 551.1150. Found: 551.1152.
