methylene group. These were required as potential inhibitors of serine-threonine kinases of interest for the treatment of cancer. 3-Nitrophenylmethanesulfonyl chloride was converted into the corresponding 2,2,2-trifluoroethoxysulfonyl ester by reaction with 2,2,2-trifluoroethanol in the presence of triethylamine/4-dimethylaminopyridine.
