To provide a method for producing a high-purity purified product useful as an intermediate for a medicine, an agrochemical, or the like, from crude 2-bromoindene obtained by dehydration reaction of indenebromohydrin(1-hydroxy-2-bromoindane) by a simple operation in a high recovery ratio.

Crude 2-bromoindene obtained by dehydration reaction of indenebromohydrin is recrystallized using a mixed solvent of an aliphatic hydrocarbon solvent such as heptane and an alcohol such as methanol.
