実験手順

A 100-mL round-bottomed flask equipped with a reflux condenser was charged with 136b (600 mg, 1.5 mmol), bis(pinacolato)diboron (1.2 g, 4.5 mmol), Pd2(dba)3 (137 mg, 0.15 mmol), X-phos (71 mg, 0.15 mmol), potassium acetate (294 mg, 3.0 mmol), and 1,4-dioxane (20 mL). After three cycles of vacuum/argon flush, the mixture was heated at 70° C. for 2 h. It was then filtered and the filtrate was evaporated under reduced pressure. The residue was washed with petroleum ether to afford 136c (520 mg, 93%) as a white solid, which was used directed without further purification. MS-ESI: [M+H]+ 373.1
