Procedure

To a solution of 1-(4-bromophenyl)cyclopropanecarbonitrile (600 mg, 0.003 mol), 3-(trifluoromethyl)-1H-pyrazole (441 mg, 0.00324 mol) in toluene (2 mL, 0.02 mol) and N,N-dimethylformamide (3 mL, 0.04 mol) were added (1S,2S)-N,N′-dimethylcyclohexane-1,2-diamine (77 mg, 0.00054 mol), copper(I) iodide (51 mg, 0.00027 mol), and potassium carbonate (784 mg, 0.00567 mol). The mixture was microwave irradiated at 200° C. for 60 minutes and then filtered. The filtrate was dilluted with methanol, and the product from the filtrate was isolated and purified using prep-HPLC. Additional product could be obtained from the precipitate by dissolving the precipitate in EtOAc, washing with satd. NaHCO3, brine, drying with MgSO4, and concentrating for purification.
