Reaction Conditions

Reaction Steps

5.4 g (21.1 mmol) of 9-bromoanthracene, 2.6 g (21.1 mmol) of phenylboronic acid, 60 mg (0.21 mmol) of Pd(OAc)2 (0), 10 mL (20 mmol) of an K2CO3 aqueous solution of 2M, 263 mg (0.84 mmol) of P(o-tolyl)3, and 20 mL of 1,2-dimethoxyethane (abbreviation: DME) are mixed, and then stirred for 9 hours at 80° C. After reaction, a precipitated solid was collected by suction filtration. Subsequently, the solid was dissolved in toluene and then filtered through Florisil®, celite, and alumina. After a filtrate was washed with water and saturated saline, it was dried with magnesium sulfate. After natural filtration, when the filtrate is condensed, 21.5 g of 9-phenylanthracene which is a target substance was obtained as a light brown solid at a yield of 85% (Synthesis Scheme (f-1)).
