Reaction Conditions

Reaction Steps

Added to a solution of 100 mg (0.34 mmol) of 3-(3,4-dihydro-6,7,8-trimethoxy-2-naphthyl)prop-(2E)-enoic acid synthesized by the process described in Referential Example 6 in toluene (2 ml) was 102 mg (0.41 mmol) of 2,3-dichloro-5,6-dicyano-p-benzoquinone, and the mixture was stirred for 1 hour and 30 minutes at 100° C. The reaction mixture was concentrated under reduced pressure, and the resultant crude oil was purified by column chromatography on silica gel, thereby obtaining 88 mg (yield: 88%) of crude crystals of the title compound. The crude crystals were recrystallized from chloroform-hexane, thereby obtaining a pale red crystalline powder.
