A 0.25 mol/L 1,3-cyclohexanedione/50% sulfuric acid solution was placed in a 200-mL container purged with nitrogen. Then, a 0.25 mol/L phenylhydrazine/50% sulfuric acid solution was added dropwise into the container under stirring at 20000 rpm by CLEARMIX (manufactured by M Technique Co., Ltd.) while the temperature of the liquid in the container was maintained at 25° C. As a result of HPLC analysis, the production rate of 1,2,3,4-tetrahydrocarbazol-4-one was 24% or less.
