Procedure

In a microwave vial was dissolved 2H-1,2,3-triazole (0.22 mL, 3.8 mmol) and CuI (26 mg) in DMF (4 mL). The reaction mixture was degassed with N2 and 3-bromo-4-methylpicolonitrile (300 mg, 1.5 mmol) was added followed by trans-N,N′-dimethyl-1,2-cyclohexanediamine (41 μL, 0.3 mmol) and Cs2CO3 (844 mg, 2.6 mmol). The reaction mixture was heated at 120° C. for 1 h in a microwave reactor. Then H2O was added and the mixture extracted with EtOAc. The combined organic layers were dried (MgSO4). Purification via silica gel chromatography (0-50% EtOAc in heptane) gave the title compound (112 mg, 27%). MS (ESI) mass calcd. for C9H7N5, 185.2; m/z found 186 [M+H]+.
