実験手順

320 mg (2.0 mM) of the (2S,5S)-5-propoxy-2-hexanol obtained in Reference Example 1 was dissolved in 15 ml of anhydrous toluene. Thereto was added metallic sodium with stirring at room temperature. To the mixture was added 478 g (1.5 mM) of 3-chloro-6-(4-octyloxyphenyl)pyridazine. The resulting mixture was refluxed for 3 hours. The reaction mixture was cooled and mixed with water and toluene. The toluene layer was separated and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography [eluting solvent: n-hexane-ethyl acetate (4:1)] to obtain 190 mg of the title compound.
