実験手順
An intermediate compound was prepared by the same method described in Example 6 except that 2-methoxymethoxy-5-methylbenzaldehyde (1.3 g) synthesized in the above-described Synthesis Example 3 was used instead of 2,6-dimethylbenzaldehyde (0.65 g). A 6 N hydrochloric acid solution (1 mL) was added to a tetrahydrofuran solution (30 mL) of the intermediate compound, and the mixture was stirred at 25° C. for 12 hours. After confirmation of the degree of reaction progress by TLC, the reaction was quenched with an aqueous solution of sodium hydrogen carbonate, and the organic phase was extracted with ethyl acetate. The resulting organic phase was dried over anhydrous magnesium sulfate, concentrated, and recrystallized to obtain 2.0 g (yield: 84%) of [4-(2,2-diphenylvinyl)phenyl]-(2-hydroxy-5-methylphenyl)methanone (12) as white crystals. The structure of Product 12 was confirmed by 1H-NMR. Table 1 shows optical characteristics and practical utility of Product 12.
