Triethylamine (0.28 ml, 2.00 mmol) was added to a mixture of 1-methyl-5-(tributylstannanyl)-1H-1,2,3-triazole (781 mg, 2.1 mmol), methyl 4-bromobenzoate (430 mg, 2.0 mmol), and BIS(TRIPHENYLPHOSPHINE)PALLADIUM(II) CHLORIDE (70.2 mg, 0.10 mmol) in toluene (10 ml) to give a yellow suspension. The reaction mixture was purged with N2, sealed and stirred at 100° C. for 3 hr. Potassium fluoride (465 mg, 8.00 mmol) and MeOH (2 mL) were added. The mixture was stirred at RT for 2 h, filtered on celite, and rinsed with EtOAc. The combined filtrates were concentrated and the residue was purified on a 25M biotage column to give 0.5 g of methyl 4-(1-methyl-1H-1,2,3-triazol-5-yl)benzoate as a tan solid.
