Reaction Steps

A mixture of 1H-1,2,4-triazole (122 mg, 1.78 mmol, Aldrich), K3PO4 (751 mg, 3.53 mmol, Aldrich), Copper(I) iodide (33.7 mg, 0.177 mmol, Alfa-Aesar), 1-bromo-4-iodobenzene (500 mg, 1.78 mmol, Aldrich), (1S,2S)—N1,N2-dimethylcyclohexane-1,2-diamine (25 mg, 0.18 mmol, Strem) and DMSO (2 mL) was purged with Argon and then heated under microwave condition at 140° C. for 30 min and then at 160° C. for 30 min. The reaction mixture was diluted with H2O and extracted with EtOAc (2×). The organic layers were combined and concentrated in vacuo to a brown oil. The solid was purified by flash chromatography (SiO2, 0-100% EtOAc in hexanes) to yield 195 mg of desired product as a white solid. MS (ESI) 224 (M+H).
