실험 절차
A mixture of 4-phenyl-phenyl magnesium bromide (prepared from 4-bromobiphenyl (7.75 g, 33 mmol) and magnesium turnings (0.83 g, 35 mmol) in 40 mL ether) and cyanuric chloride (4.00 g, 21.7 mmol) in benzene (90 mL) was stirred at 0° C. for 90 minutes. The reaction was evaporated to dryness, and the residue was flash chromatographed on silica gel with 50% hexanes/methylene chloride to provide the desired compound (2.80 g, 43%).
