Versuchsvorschrift

To a solution of 1-[(4-bromophenyl)methyl]-5-methyl-1H-1,2,3-triazole-4-carboxylic acid (0.2 g, 0.67 mmol) in DME (10 mL) were added (2-chlorophenyl)boronic acid, (0.137 g, 0.88 mmol), Pd tetrakis (20 mg, 10% mol/mol) and a 2M solution of sodium carbonate (1.34 mL, 4 eq). The reaction was heated at 85° C. for 48 hours. After evaporation of DME, water was added and the reaction was extracted with ethyl acetate (2×40 mL). The aqueous phase was adjusted to PH=7 by addition of a 1N HCl solution and extracted with ethyl acetate. The combined organic phases were dried over sodium sulphate and evaporated in vacuo to give the title compound as a solid (117 mg, 40%). HRMS calculated for C17H14ClN3O2(M+H)+328.0853. found: 328.0865, Rt: 2.04 min.
