Abstract:
The present invention refers to a process for producing 5-[4-(2-hydroxy-2-methyl)-1-oxo-prop-1-yl]-3-[4-(2-hydroxy-2-methyl)-1-oxo-prop-1-yl-phenyl]-2,3-dihydro-1,1,3-trimethyl-1H-indene (dimer isomer 5) that comprises the acylation of cumene in the 4-position with an isobutyryl halide, followed by benzylic halogenation and dimerization (cyclization) of the resulting product.
