YieldReaction ConditionsOperation in experiment
58% With tetrakis(triphenylphosphine) palladium(0); caesium carbonate In ethanol; water for 0.5h; Microwave irradiation; Heating; 4.49 5.4.48. 4-{3-[1-(5-Ethylpyrimidin-2-yl)piperidin-4-yl]-3H-[1,2,3]triazolo[4,5-c]pyridin-6-yl}-2-methylbenzoic acid (31g) General procedure: To a solution of 151 29a (500mg, 1.29mmol) in 127 EtOH (12.9mL) were added 169 2,5-difluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (549mg, 1.93mmol), 170 Pd(PPh3)4 (74.5mg, 0.0645mmol) and 2M 24 Cs2CO3 aqueous solution (1.29mL). After the mixture being stirred at 150°C under microwave irradiation for 30min, 2M Cs2CO3 aqueous solution was added to the mixture. The aqueous layer was washed with EtOAc, neutralized with 1M HCl aqueous solution and extracted with 10% MeOH in 59 CHCl3. The organic layer was separated, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. The resulting solid was washed with EtOAc-hexanes to afford 171 31b as a colorless solid (290mg, 48% yield).

73% With dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; potassium acetate In 1,4-dioxane at 90℃; Inert atmosphere; 1-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzoic acid (102) (0405) Potassium acetate (1473 mg, 15.00 mmol), bis-(pinacolato)-diboron (1523 mg, 6.00 mmol) and bis(diphenylphosphine) ferrocene dichloropalladium (II) complex with dichloromethane (183 mg, 0.25 mmol) was added to an anhydrous solution of 4-bromo-2-methylbenzoic acid (1075 mg, 5.00 mmol) in dioxane (180 mL) under anhydrous conditions in an atmosphere of nitrogen. The mixture was stirred at 90 °C overnight. The reaction was then quenched with water and extracted with ethyl acetate. The combined organic layers were dried over magnesium sulfate, filtered and concentrated. The residue was purified by flash column chromatography on silica gel (eluent: (0406) dichloromethane/ethyl acetate, 10-100%) to give the title compound as a white solid (970 mg, 73%).
