Participants

Reaction Steps

To a solution of 2-heptyl-5-(hydroxymethyl)-imidazole (10.0 g, 51 mmol) in EtOH/1,4-dioxane (1:1; 600 mL) was added N-chlorosuccinimide (7.9 g, 59 mmol). After being stirred for 1 hour at room temperature the solvents were removed on a rotary evaporator and the solid residue was partitioned between ethyl acetate and water (300 mL each). The organic phase was washed with water (150 mL), dried (MgSO4), filtered and concentrated to afford 12.4 g crude product. Recrystallization (1:1 EtOAc/hexane, 60 mL) gave 5.7 g (45%) of white crystals; m.p. 134°-140°. NMR (200 MHz, CDCl3 /CD3OD) δ4.50 (s, 2H); 4.00-3.80 (br s, 2H); 2.65 (t, 2H, 5 Hz); 1.80-1.60 (m, 2H); 1.40-1.20 (m, 8H); 0.90-0.80 (m, 3H). Mass Spec. 230.
