Procedure

Propyl p-hydroxybenzoate and phthalic dichloride are allowed to react and treated in a similar procedure to Example 4. The residue obtained is recrystallized from hexane and recrystallized from ethyl acetate-chloroform (1:1) to yield di(p-propoxycarbonylphenyl)phthalate, m.p. 87°-89° C., as white crystals.
