Reaction Steps

A mixture of tert-butyl 4-(5-chloro-4-iodo-2-methoxybenzoyl)piperazine-1-carboxylate (300 mg, 0.56 mmol), phenylboronic acid (82 mg, 0.67 mmol), Pd(PPh3)4 (129 mg, 0.1 mmol), Na2CO3 (180 mg, 1.68 mmol) in 1,4-dioxane (10 mL) and water (2 mL) was stirred at reflux under argon for 16 h. The mixture was allowed to cool to room temperature and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (petroleum ether/ethyl acetate=30:1) to afford the desired product (219 mg, 80% yield).
