Default Problem with the Claisen condensation

Hi Marcin,

the problem which you encountered, is an old topic. The reason is due
to the unprotected phenolic hydroxyl group, since due to tautomerism
this reaction does not takes place.
But to obtain successfully your target molecule, you have to do this
reaction after you have protected the phenolic hydroxyl group. Then
the reaction will work. See the following patent: Thorton, D.A.; et
al: US Patent Appl.
US 3,281,493 (also as corresponding British Patent GB 948,494). This
patent is cited in Chem. Abstr. Vol. 60, 1964, 11950h.
