After addition of the entire amount of 2-acetylaniline, the system was refluxed for 16 hours and then cooled to room temperature. After cooling, the ethanol was removed by stripping. Water was then added to the residue to give a precipitate. The precipitate was filtered and dried to give a pale yellow solid, m.p. 55°-60° C.
