Methyl iodide → 2-Nitro-4-phenylmethoxyanisole

Participants

Reaction Steps

2-Nitro-4-phenylmethoxy-phenol is methylated by contacting it with a slight molar excess of potassium carbonate and a large molar excess of methyl iodide and tetrabutylammonium bromide (TBAB) in an inert solvent (such as acetone) and refluxed for 8 to 15 hours, preferably 12 hours. After cooling, filtration and evaporation of the solvent, the residue is purified by conventional means to give 2-nitro-4-phenylmethoxyanisole, which in turn is hydrogenated to give the corresponding aniline of Formula 12.
