2-Nitrophenols spontaneously rearrange during alkylation with 2-bromo-2-methylpropionamide in the presence of cesium carbonate in acetonitrile to the corresponding 2-hydroxy-2-methyl-N-(2-nitrophenyl)propionamides. Upon reduction of 2-aryloxy-2-methylpropionamides, which were obtained from 2-nitrophenols in three steps, with borane dimethyl sulfide complex in THF, a Smilesrearrangement was observed as well
