The Z-isomer (200~) obtained above was dissolved in a 50% aqueous phosphoric acid solution (2 ml), and a heating reaction was performed at 100°C for 20 hours. The product was extracted, washed with water, and concentrated according to the post-reaction method, and a portion of the residue was subjected to high performance liquid chromatography, and the ratio of E-isomer and Z-isomer was determined to be 58:2.
It was 7. This mixture was subjected to preparative high-performance liquid chromatography, and the above E-isomer and Z-isomer were each collected at 19, 5-5 Oharano Kamisato Torimi-cho, Nishito-ku, Kyoto City.
