Procedure

To a methylene chloride (6 mL) solution of (E)-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzylidene)-6-oxohexanoic acid ethyl ester (231 mg), 3-fluorobenzylamine (88.7 μL), acetic acid (0.5 mL) and sodium triacetoxy borohydride (165 mg) were added one by one. After agitating the reaction solution at room temperature overnight, a saturated sodium bicarbonate water and ethyl acetate 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, elution solvent; heptane-ethyl acetate=1:1->ethyl acetate->ethyl acetate:ethanol=10:1), and 173 mg of the title compound was obtained. The physical properties of the compound are as follows.
