실험 절차

4-bromo-2-chlorobenzoic acid (0.4 g), 5-chloro-2-methoxybenzoic acid (0.4 g), Pd(dppf)Cl2 (0.12 g), sodium carbonate (0.9 g), dioxan (15 ml) and methanol (5 ml) were charged to a flask and heated at reflux for 16 h. Cooled to room temp and filtered (hyflo). The filtrate was concentrated in vacuo, then dissolved in ethyl acetate. The suspension was made basic by addition of dilute NaOH. The aqueous layer was separated and acidified using 2M HCl, extracted with EtOAc, dried (MgSO4) and evaporated in vacuo to give the sub-title compound Yield 0.4 g
