Versuchsvorschrift
A solution of 1-(4-Bromo-phenyl)-3-chloro-propan-1-ol* (1.5 g, 6.01 mmol) and imidazole (1.23 g, 18.03 mmol) in dimethylformamide (18 ml) was heated at 100° C. for 18 hrs then partitioned between water and ethyl acetate. The organic extracts were combined, dried (MgSO4), filtered, concentrated and purified by column chromatography (SiO2), eluting with methanol:dichloromethane (2:98) to methanol:dichloromethane (6:94) to afford the title compound (0.75 g, 44% yield). LC/MS: (PS-B3) Rt 2.48 [M+H]+ 281.14, 283.11. *This starting material can be made by the method described in Example 43A.
