Procedure

A mixture of 40 parts of N-(3-acetyl-2,6-dimethylphenyl)acetamide and 300 parts of concentrated hydrochloric acid was stirred for 20 hours at reflux temperature. After cooling, the reaction mixture was treated with ammonium hydroxide. The product was extracted twice with dichloromethane. The combined extracts were washed with water, dried, filtered and evaporated, yielding 35.5 parts (100%) of 1-(3-amino-2,4-dimethylphenyl)ethanone as a residue (int. 111).
