1-aryl-3,4-dihydro-1H-naphthalene-2-one is prepared by isomerizing an epoxy compound represented by the following general formula,
wherein a is an integer of 0 to 5, b is an integer of 0 to 4, and R
1
to R
6
are hydrogen atoms or substituents such as alkyl groups,
in an organic solvent in the presence of magnesium sulfate. This process makes it possible to prepare the 1-aryl-3,4-dihydro-1H-naphthalene-2-one safely and in a high yield without using highly explosive compounds such as lithium perchlorate.
