Participants

Reaction Steps

The compound (t-butyl 2-(6-bromo-2-naphthyloxy)-4-nitrobenzoate) (1.78 g) obtained in a previous production example, zinc cyanide (0.33 g) and tetrakis(triphenylphosphine)palladium (0) (690 mg) were reacted for 12 hours at 100° C. in N,N-dimethylformamide. After cooling to room temperature, toluene and ethyl acetate were added, the organic layer was washed with 2 N ammonia water and saturated saline and dried over magnesium sulfate, and the solvent was distilled off. The residue was purified by silica gel chromatography (300 g, hexane:ethyl acetate=6:1) to obtain 1.14 g of t-butyl 2-(6-cyano-2-naphthyloxy)-4-nitrobenzoate.
