20 mmole of 5-mercapto-1H-1,2,3-triazole (sodium salt) was dissolved in 20 ml of ethanol in stirring. 10 mmole of 1,4-diiodobutane was added dropwise to the solution of 5-mercapto-1H-1,2,3-triazole (sodium salt), and stirred overnight. After the solvent was evaporated in vacuum, the residual was washed with 50 ml pure H2O for three times, and then with 50 ml hexane for 3 times. At last, the residual was dried in oven at 60° C. for 24 hours. 1.8 g product was obtained as white solid. Yield: 70%. 1H NMR (DMSO): δ (ppm) 7.86 (2H, s), 2.85 (4H, m), and 1.66 (4H, m).
