Sulfuric Acid → Methyl 3-amino-2,4,6-trimethylphenylacetate

Participants

Reaction Steps

To a solution of 3-cyanomethyl-2,4,6-trimethylaniline (see Example 14, procedure C) (5 g, 28.7 mmol) in methanol (30 mL) was added concentrated sulfuric acid (30 mL) with cooling. The resulting mixture was heated under reflux for 8 h before it was allowed to cool to rt and diluted with water (100 mL). The mixture was stripped off methanol and the residue was basified with sodium carbonate and then extracted with ethyl acetate. The organic layer was worked up and concentrated as usual to give the desired compound as an oil (5.2 g, 88%).
