Versuchsvorschrift

1-(Cyclopropylmethyl)-4-(trifluoromethyl)-1H-benzotriazol-5-yl trifluoromethanesulfonate (221 mg, 0.568 mmol) and (6-chloro-2-fluoropyridin-3-yl)boronic acid (130 mg, 0.738 mmol, 1.3 equiv) were dissolved in degassed dioxane (5.6 mL) and treated with potassium phosphate (0.37 mL, 2 M aqueous, 0.74 mmol, 1.3 equiv) and palladium tetrakis(triphenylphosphine) (98 mg, 0.085 mmol, 0.15 equiv). The mixture was placed into a preheated oil bath at 90° C. for 3 hours, cooled to ambient temperature, diluted with ethyl acetate (40 mL) and washed with sodium bicarbonate (2×30 mL, aqueous saturated). The combined organic extracts were dried with sodium sulfate, filtered and concentrated in vacuo. The residue was purified by silica gel gradient chromatography (100:0 to 70:30; hexanes:ethyl acetate), providing the titled compound.
