Procedure

A mixture of 2 parts of 4-ethyl-2-nitrobenzenecarbonitrile, 31.6 parts of ethanol, 27.8 parts of hydrogen peroxide (30%) and 1.7 ml of sodium hydroxide 6N was stirred for 1 hour at room temperature. The reaction mixture was diluted with water and the product was extracted with dichloromethane (3×). The combined extracts were washed with water, dried, filtered and evaporated. The residue was crystallized from 2,2'-oxybispropane. The product was filtered off and dried, yielding 1.3 parts (60.9%) of 4-ethyl-2-nitrobenzamide; mp. 175.0° C. (interm. 4).
