The reaction of aniline 3.8 g (0.041 mol) with phthalic anhydride 4.0 g (0.041) mol in 100 ml of refluxing glacial acetic acid for 3 hours, followed by precipitation from water, filtration and vacuum drying at 120° C., afforded an 8.2 g (91%) yield of product, m.p. 205°-9° C. (from ethanol). Lit. reports m.p. 210° C. ("Dict. Org. Cpds", 5, 2740(1965), Oxford Univ. Press, N.Y.). Anal. Calcd. for C14H9NO2 : C, 75.33; H, 4.06. Found: C, 75.10; H, 4.17%. Ir(KBr): 1765, 1700, and 1375 cm-1 (imide).
