Reaction Steps
Copper(I) iodide (19.1 mg, 0.1 mmol), benzoxazole (119 mg, 1.0 mmol), iodobenzene (612 mg, 3.0 mmol), t-BuOK (224 mg, 2.0 mmol), and DMF (1.0 mL). After column chromatography (hexanes, then 10% ethyl acetate in hexanes) and preparative HPLC (5% ethyl acetate in hexanes) 119 mg (61%) of 2-phenylbenzoxazole is obtained. Table I, entry 3.
