Reaktionsschritte
A solution of 1,2-epoxyhexane (2.0 mL, 17 mmol) and imidazole (1.08 g, 16 mmol) in acetonitrile (14 mL) was stirred at reflux for 19 h. The mixture was concentrated, taken up in 2.5 M aqueous hydrochloric acid (15 mL), washed with ethyl acetate (3×6 mL), basified with sodium carbonate and extracted with ethyl acetate (3×6 mL). The combined extracts were dried (Na2SO4) and concentrated. The residue was purified by flash column chromatography (SiO2, CH2Cl2-methanol-ammonium hydroxide 80:20:1) to give 1-(1H-imidazol-1-yl)-2-hexanol as a colorless oil, 1.68 g, 63% yield. NMR spectrum was consistent with structure. MS EI: M+• 168.1259 (M+• 168.1263).
