The residue was recrystallized from ethanol whereby the desired product, m.p. 160°-162° C., was obtained. By substituting 3-fluorophthalic anhydride, 4,5-dichlorophthalic anhydride, and 4-methylphthalic anhydride for the phthalic anhydride of this example, the compounds set forth in Table XX below were obtained.
