反応手順
To a mixture of 4-pyridylboronic acid (500 mg, 4.06 mmol), 1-iodo-4-nitrobenzene (1.01 g, 4.06 mmol) and Pd(Ph3P)2Cl2 (140 mg, 0.199 mmol) in dioxane (15 mL), a solution of Na2CO3 (1.00 g, 9.43 mmol) in H2O (10 mL) was added. The mixture was stirred at 100 C for 20 h. Water and EtOAc were added. Organic phase was separated, washed with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo. The residue was purified by a silica gel column on ISCO, eluted with 20-100% EtOAc in hexanes to give 4-(4-nitrophenyl)pyridine as a solid (342 mg).
