実験手順

p-Chlorophenylpropiolic acid (3.3 g) and propiolic acid (7.6 g) in acetic anhydride (80 ml) were refluxed for 12 hr. The solution was concentrated (to 40 ml) and the precipitate which formed on cooling was recrystallised from acetone to give 6-chloro-2,3-naphthalenedicarboxylic anhydride (2.3 g) m.p. 220°.
