Reaction Steps

To the solution of 2H-1,2,3-triazole (CAS number 288-36-8; 0.23 g, 3.33 mmol) in 1,4-dioxane (4.0 ml) was added cesium carbonate (1.0 g, 3.33 mmol), trans-1-N,2-N-dimethylcyclohexane-1,2-diamine (0.047 g, 0.33 mmol), copper(I) iodide (0.015 g, 0.08 mmol) and 2-bromo-3,6-difluorobenzoic acid (CAS number 124244-65-1; 0.40 g, 1.68 mmol). The reaction was stirred at 120° C. for 30 minutes and was then poured into water (10 ml) and extracted with ethyl acetate (2×30 ml). The organics were washed with brine, dried over sodium sulfate and concentrated in vacuo. The resulting residue was purified by column chromatography (silica, 0-5% methanol/DCM) to afford the title compound.
