(S)-N-[(1S,2S)-2-Benzylamino-1-(4-hydroxyphenyl)-3-methylbutyl]-1,1-dimethylethane-2-sulfinamide

The title compound, C22H32N2O2S, was obtained by dehydroxylation and deacetylation of 4-{(1S,2S)-2-(benzylhydroxyamino)-3-methyl-1-[(S)-2-methylpropane-2-sulfinylamino]butyl}phenyl acetate, which was derived from reductive crosslinking of nitrone with N-tert-butanesulfinylimine. The crystal structure shows that the molecules are linked by O—H⋯O hydrogen bonds.
