The reaction was treated with Pd(PPh3) (243 mg (0.2 mmol) and then purged with bubbling for 5 minutes in a sealed vessel and then heated to reflux for 2 h. The reaction mixture was cooled to 23 °C, filtered, and solid rinsed with EtOAc. The organic layers were separated, dried and concentrated. Purification via FCC (ethyl acatate/hexanes, 0-30percent) afforded methyl 5-fluoro-2-(1 H-pyrazol-5-yl)benzoate (415 mg, 44percent).

YieldReaction ConditionsOperation in experiment
52% With tetrakis(triphenylphosphine) palladium(0); In toluene; at 150℃; for 0.5h;Microwave irradiation; j0363] To a solution of methyl 2-bromo-5-fluorobenzoate (1.1 g, 4.8 mmol) and <strong>[145214-05-7]2-(tri-n-butylstannyl)oxazole</strong> (1.3 mE, 6.2 mmol) in toluene (14 mE) was added Pd(PPh3)4 (550 g,0.476 mmol), and the reaction mixture was heated via microwave heating to 150 C. for 30 mm. The reaction mixture was diluted with water and extracted with EtOAc. The combined organic layers were dried over Mg504, filtered and concentrated. Purification via silica gel chromatography (0-40% EtOAc in hexanes, followed by a second column 0-10% EtOAc in hexanes) gave the title compound (553 g, 5 2%).
