Procedure

N-(5-ethoxy-2-methylphenyl)-2-oxo-3-methylbutanamide (8.8 g, 35.3 mmol) was dissolved in m-dichlorobenzene (100 ml). Aluminum chloride (20.6 g, 155 mmol) was added to the solution, and the mixture was placed in a bath of 100° C. and stirred for 1.5 hours. The reaction mixture was poured in ice--water, and the precipitate was collected by filtration. To the filtrate, a mixture of chloroform--methanol (5:1) was added. The organic phase was extracted, and dried. The solvent was distilled off under reduced pressure. The resultant residue was recrystallized from methanol--ether to obtain 3.3 g in total of the title compound as yellow powder (46.2%).
