A method is described for producing a compound having the formula (I)
or an admixture comprising a compound having the formula (I),
having the following steps:
dissolving an indanone having the formula (II) in a solvent or in an admixture which contains a solvent, the solvent being selected from the group of solvents which form an azeotrope with water,
converting the indanone having the formula (II) with an aromatic aldehyde having the formula (III) in the presence of at least one organic base, according to the drawing:
