실험 절차

Kinetin (2 g, 9.3 mmol), 1-bromo-2-chloroethane (1.3 g, 9.1 mmol) and K2CO3 (2.5 g, 24 mmol) were mixed in 100 ml dimethylsulfoxide (DMSO) for 18 h. The reaction mixture was poured onto 200 ml drift ice and then extracted in ethyl acetate and dried over Na2SO4. The ethyl acetate layer was evaporated in vacuo. The pure product of white powder character was recrystallised from methanol. Yield: 80%. 1H NMR (DMSO-d6): 4.07 (2H, t, J=5.82), 4.52 (2H, t, J=5.82), 4.70 (2H, s (br)), 6.23 (1H, d, J=2.67), 6.35 (1H, m), 7.53 (1H, d, J=2.67), 8.22 (2H, m), 8.25 (1H, s)
