Reaction Steps

A reaction mixture was prepared containing 68.7 g. of 3-methylthio-4-nitroveratrole, 261 g. sodium dithionite (Na2S2O4), 1500 ml. of ethanol and 2250 ml. of water. The reaction mixture was heated at reflux temperature for about 1 hour and then cooled. The reaction mixture was then made basic with potassium carbonate and the resulting alkaline solution concentrated in vacuo to one-half its original volume. The aqueous solution was extracted twice with 2 l. portions of ether. The ether extracts were combined, dried, and the ether removed therefrom by evaporation in vacuo. The solid residue, comprising 2-methylthio-4,5-dimethoxy aniline formed in the above reaction, was recrystallized from a benzene-hexane solvent mixture to yield 33.6 g. of crystalline material melting at 69°-72° C.
