Reaction Conditions

Reaction Steps

2-Chloro-6-trifluoromethylpyridine (451 mg, 2.5 mmol), ethyltrifluoroborate potassium salt (374 mg, 2.75 mmol), palladium acetate (11 mg, 0.05 mmol), di(1-adamantyl)-n-butylphosphine (27 mg, 0.075 mmol), and cesium carbonate (2.4 g, 7.5 mmol) were suspended in a mixture of toluene and water (10:1, 10 mL). After flushing the vessel under a stream of nitrogen gas for 5 minutes, the reaction tube was sealed and then heated at 100° C. for 18 hours. On cooling, the mixture was partitioned between DCM (15 mL) and water (15 mL). The separated aqueous phase was extracted with DCM (2×15 mL) and the combined organic phases were passed through a phase separator and concentrated in vacuo, affording a yellow oil which was used without further purification (460 mg, crude)
