Reaction Conditions

Reaction Steps

To a solution of 21.5 g. (0.14 mole) of 2-phenylimidazole in 60 ml. dry dimethylformamide and 300 ml. dry tetrahydrofuran under nitrogen atmosphere there is added at room temperature 9.0 g. (0.19 mole) of 50% sodium hydride/mineral oil suspension. The resulting mixture is stirred and heated to 50° C. for about 3 hours. After cooling to room temperature the resulting mixture is treated dropwise with a solution of 40.5 g. (0.18 mole) of (±)-1-bromo-3,7-dimethyloctane in dry tetrahydrofuran. The reaction mixture is stirred over night at room temperature and the resulting mixture is filtered and the residue washed with tetrahydrofuran. The combined filtrate is concentrated in vacuo to an oil, the oil is then dissolved in methylene chloride, washed with water, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to yield an oily product. Distillation gave (±)-1-(3,7-dimethyloctyl)-2-phenylimidazole; b.p. 150° to 157° C. at 0.2-0.16 mm.
