Sodium Carbonate → 2-(2-Formyl-biphenyl-4-yloxy)4-trifluoromethyl-benzonitrile

Participants

Reaction Steps

To a mixture of 2-(4-bromo-3-formyl-phenoxy)-4-trifluoromethyl-benzonitrile (1.76 g, 4.76 mmol) and Pd(dba)3 (21.8 mg, 5 mole %) in dimethoxyethane (15 ml) was added a solution of phenylboronic acid (609 mg, 5 mmol), triphenylphosphine (15 mg, 12 mole %) and sodium carbonate (530 mg, 5 mmol) in water (10 ml). The mixture was refluxed for 3 h. The solvent was evaporated off and the aqueous layer was extracted with dichloromethane. The extracts were dried with MgSO4 and filtered through silica. Evaporation yielded a brown solid (1.73 g, 99%).
