Reaction Steps

A mixture of diethyl[(3-bromophenyl)(fluoro)methyl]phosphonite (5.5 g, 17.0 mmol), 2,6-dimethylpiperidine (10 mL), and 1-(difluoromethoxy)-4-ethynylbenzene (3.38 g, 20.4 mmol) was degassed with argon for 5 minutes. Then, tetrakis(triphenylphosphine) palladium (0) (983 mg, 0.85 mmol) was added and the mixture was stirred at 80° C. for 5 hours. The mixture was poured into water and extracted with EtOAc. The organic extracts were dried over MgSO4. Evaporation and purification by ICSO (hexane/EtOAc 1/1) gave diethyl[(3-{[4-(difluoromethoxy)phenyl]ethynyl}phenyl)(fluoro)methyl]phosphonite (3.6 g) as a clear oil; MS m/e (M+H)+ 413.
