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 R1 to R6 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.
