PROBLEM TO BE SOLVED: To provide an improved method for the [2+2+2] cyclotrimerization reaction in an aqueous solution using a water-soluble transition metal catalyst. SOLUTION: The synthesizable compound is a substituted aromatic compound expressed by general formula (R<SB>1</SB>is H or -CH<SB>2</SB>OH; and R<SB>2</SB>is -CH<SB>2</SB>OH, -COCH<SB>3</SB>, -CO<SB>2</SB>CH<SB>3</SB>, (CH<SB>2</SB>)<SB>2</SB>OH, -CH<SB>2</SB>NH(CH<SB>3</SB>), -C(CH<SB>3</SB>)<SB>2</SB>OH or -CH<SB>2</SB>N(CH<SB>3</SB>)<SB>2</SB>).
