7.9 g (21.9 mmol) of 3-(anthracen-9-yl)-5-bromobenzaldehyde, 5 g (24.4 mmol of pyridine-3-boronic acid neopentylglycol ester, 0.85 g (3 mol %) of tetrakis(triphenylphosphine) palladium (0), and 5.17 g (48.8 mmol) of sodium carbonate were dissolved in 90 ml of tetrahydrofuran/H2O in a volume ratio of 2/1. The solution was reacted at 80° C. for 12 hours. The acquired reactant was extracted with ethyl acetate and treated under reduced pressure to remove the solvent. The extract was separated through a column, obtaining 7.24 g (Y=91%) of a white solid.
