6-Acylbenzoxazolinones I (R = H, Me, R1 = Me, CH2Cl, Et, Ph, CH2Ph, 2-thienyl) were prepared in 25-75% yield by treating 2-benzoxazolinone or 1-methyl-2-benzoxazolinone with R1CO2H and polyphosphoric acid. I (R = H, Me, R1 = CHO) was similarly prepared with hexamethylenetetramine and polyphosphoric acid. I had analgesic activity comparable to that of benzoxazolinone and aspirin, but lower antiinflammatory activity.
