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<SUP>1 </SUP>to R<SUP>6 </SUP>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.
