실험 절차

4-Iodo-3-methoxy-benzoic acid methyl ester (292 mg, 1 mmol) and para-fluorophenylboronic acid (160 mg, 1.14 mmol) and Pd(PPh3)4 (80 mg, 0.069 mmol) and Cs2CO3 (600 mg, 1.84 mmol) is mixed in N,N-dimethylformamide (10 mL) and degassed and then heated at 100° C. for 4 hours. After which, the mixture is allowed to cool to room temperature and an aqueous work up is performed and the residue purified to afford the desired product (240 mg, 92%).
