Procedure

A slurry of 20.9 g 2-bromo-2'-ethyl-6'-methyl propionanilide, 125 ml 95% alcohol, and 75 ml concd. ammonia was saturated with gaseous ammonia and was heated to 55° C. for 30 hours in a pressure vessel. The reaction mixture was filtered and the filtrate concentration in vacuo. The residue was dissolved in 2 M hydrochloric acid and was extracted with ethyl acetate. The acid phase was made alkaline to pH 9 and was extracted with methylene chloride to give 15.5 g of a crystallizing oil. Recrystallized from ether-petroleum ether, the compound (2-amino-2'-ethyl-6'-methylpropionanilide) melted at 68.5°-70° C.
