実験手順

To a solution of 3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzaldehyde (5 g) obtained in Example 1 in THF (60 mL) and ethanol (20 mL), 5-chloro-2-(diethoxyphosphoryl)valeric acid ethyl ester (7.6 g) and lithium hydroxide monohydrate (2.9 g) were added one by one, and the reaction solution was agitated at room temperature overnight. Water and ethyl acetate were added to the reaction solution after confirming disappearance of the starting materials, and the organic layer was partitioned. After the obtained organic layer was washed with a saturated saline solution, it was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. 3.76 g of the title compound was obtained by purifying the residue by silica gel chromatography (heptane:elution solvent:ethyl acetate=1:1), and re-crystallizing the obtained solid from a mixed solvent of ethyl acetate and hexane. The physical properties of the compound are as follows.
