1,1,1-Trifluoro-N-phenyl-N-(1H-tetrazol-5-ylmethyl)­methanesulfonamide

The reaction of 1,1,1-trifluoro-N-phenylmethanesulfonamide with bromoacetonitrile quantitatively afforded N-(cyanomethyl)-1,1,1-trifluoro-N-phenylmethanesulfonamide which reacted with sodium azide to give the corresponding [2+3]-cycloaddition product, 1,1,1-trifluoro-N-phenyl-N-(1H-tetrazol-5-ylmethyl)­methanesulfonamide, in a moderate yield.
