4-Hydroxybiphenyl → HCID 39158632, compound

Participants

Reaction Steps

To a solution of 4-phenylphenol (10.0 g, 59 mmol) in dry N,N-dimethyl-formamide (45 mL) kept under an atmosphere of nitrogen, sodium hydride (2.82 g, 71 mmol, 60% dispersion in oil) was added in portions and the reaction mixture was stirred until gas evolution ceased. A solution of m-cyanobenzyl bromide (13 g, 65 mmol) in dry N,N-dimethylformamide (45 mL) was added dropwise and the reaction mixture was stirred at room temperature for 18 hours. The reaction mixture was poured on to ice water (150 mL). The precipitate was filtered of and washed with 50% ethanol (3×50 mL), ethanol (2×50 mL), diethyl ether (80 mL), and dried in vacuo at 50° C. for 18 hours affording crude 17.39 g of 3-(biphenyl-4-yloxymethyl)benzonitrile as a solid.
