Procedure

[5-(4-Bromo-phenyl)-3-methyl-3H-[1,2,3]triazol-4-yl]-carbamic acid 1-(3-trifluoromethyl-phenyl)-ethyl ester (680 mg, 1.45 mmol), methyl 1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)cyclopropanecarboxylate (525 mg, 1.74 mmol), X-Phos (138 mg, 0.29 mmol), palladium acetate (33 mg, 0.14 mmol) and potassium phosphate tribasic (923 mg, 4.35 mmol) were mixed in toluene (10 mL). Degassed water (2 mL) was added and the mixture was degassed with argon and then sealed. The mixture was stirred at 95° C. for 5 hrs until all starting material was consumed. The mixture was extracted with ethyl acetate and water. The organic layer was washed with brine and dried. Solvents were evaporated and the residue was purified by flash column chromatography (ethyl acetate in hexanes 5% to 70% in 15 minutes, 40 g silica gel) to give an amorphous white fluffy material as 1-(4′-{1-methyl-5-[1-(3-trifluoromethyl-phenyl)-ethoxycarbonylamino]-1H-[1,2,3]triazol-4-yl}-biphenyl-4-yl)-cyclopropanecarboxylic acid methyl ester (436 mg, 53.3% yield).
