Procedure

To a THF (5 mL) solution of 3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzaldehyde (283 mg) obtained in Example 1 and 2-(diethoxyphosphoryl)-5-(tetrahydropyran-2-yloxy)valeric acid ethyl ester (480 mg), lithium hydroxide monohydrate (110 mg) was added, and the reaction solution was agitated at room temperature for 19 hours. Ethyl acetate and a saturated ammonium chloride solution were added to the reaction solution, 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. The residue was purified by silica gel chromatography (Carrier: Chromatorex™ NH and elution solvent: hexane:ethyl acetate=1:1->ethyl acetate), and 186 mg of the title compound was obtained. The physical properties of the compound are as follows.
