Versuchsvorschrift
To a mixture of 16.20 g cyclopropanmethanol in 150 ml dry DMSO 11 g sodium hydride (55%) was added and the mixture was stirred at room temperature for 30 minutes. A solution containing 37.30 g 2-(4-chloro-phenyl)-3-fluoro-pyridine in 50 mL dry DMSO was added dropwise. The reaction mixture was then stirred at room temperature for 3 h. The resulting suspension was partitioned between water and methylene chloride, the phases were separated. The organic phase was washed with brine; then dried over MgSO4 and purified by chromatography on silica gel with a gradient of heptane to heptane:ethylacetate=2:1 to yield 34.95 g (74.90%) of the title compound as yellow oil, MS 260.1 (M+H)+.
