实验过程

The compound (4-(6-cyano-2-naphthyloxy)-3-(2-formylphenyl)nitrobenzene) (800 mg) obtained in a previous production example, 2-methyl-2-butene (1.4 ml) and sodium dihydrogen phosphate dihydrate (2 g) were dissolved in acetonitrile:water (2:1, 50 ml) and then sodium chlorate (1 g) was added. After reaction for one hour at room temperature, 1 N hydrochloric acid water was added and extraction was performed with ethyl acetate. The ethyl acetate layer was washed with 1N hydrochloric acid water and saturated saline and then dried over magnesium sulfate, and the solvent was distilled off to obtain 5′-nitro-2′-(6-cyano-2-naphthyloxy)-1,1′-biphenyl-2-carboxylic acid (800 mg). This was dissolved in toluene without purification and subjected to the same process as in Production Example 1 to obtain t-butyl 2′-(6-cyano-2-naphthyloxy)-5′-nitro-1,1′-biphenyl-2-carboxylate.
