Versuchsvorschrift

6-[(3-methylbut-2-en-1-yl)amino]purine (2 g, 9.8 mmol), 1-bromo-2-chloroethane (1.4 g, 9.8 mmol) and K2CO3 (3 g, 29 mmol) were stirred in 50 ml DMSO for 12 h. The reaction mixture was poured onto ice (200 ml) and extracted in ethylacetate (50 ml). The solid residue was recrystallized from hexane to obtain white crystals. Yield: 60%. 1H NMR (DMSO-d6): 1.66 (3H, s), 1.70 (3H, s), 4.06 (2H, t, J=5.76), 4.10 (2H, s (br), H12), 4.50 (2H, t, J=5.76), 5.31 (1H, t, J=6.57), 7.767 (1H, s (br)), 8.15 (1H, s), 8.20 (1H, s).
