Acylation of hydroxy aromaticcompounds with 2-bromo-2-methylpropionamide followed by Smiles rearrangement of the resulting 2-aryloxypropionamide in a one-pot procedure produced the corresponding 2-hydroxy-2-methyl-N-arylpropionamides which can be converted to arylamines by hydrolysis. Particularly important applications of this new process were the conversions of estrone (6) and estradiol (14) to

The present invention is a process of converting a hydroxy aromatic into a 2-hydroxy-N-arylacetamide, comprising: (1) treating a reaction mixture comprising a salt of a hydroxy aromatic with an alkylating agent; and (2) treating the reaction mixture with a Smiles solvent system and raising the temperature of the reaction mixture.
