A 20 mL microwave reaction vessel equipped with a stir bar was charged with 2-isopropyl-5-methyl-cyclohexanecarboylic acid [2-(2-bromo-phenyl)-ethyl]-amide (1.54 g, 4.2 mmol), CuCN (0.60 g, 6.4 mmol) and NMP (10 mL). The reaction vessel was subjected to microwave at 180° C. for 40 minutes. The reaction mixture was transferred to a round bottom flask and concentrated. The residue to purified by flash chromatography on silica gel (10% ethyl acetate/hexane for elution) to give a colorless solid (1.25 g, 81%).
