Versuchsvorschrift

To a DMF (5.0 mL) solution of ((E)-5-chloro-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzylidene)valeric acid (5-morpholin-4-yl-indan-1-yl)amide (2.80 g), sodium hydride (40% mineral oil content, 267 mg) was added at 0° C., and the reaction solution was agitated for 15 minutes. 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 organic layer was washed with a saturated saline solution, it was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. By purifying the obtained residue by silica gel chromatography (elution solvent: a heptane-ethyl acetate system, ethyl acetate-ethanol system), 2.12 g of (E)-3-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzylidene)-1-(5-morpholin-4-yl-indan-1-yl)piperidin-2-one racemate was obtained. Next, this compound (140 mg) was separated in CHRIALPAK™ AD-H available from Daicel Chemical Industries, Ltd. (2 cm×25 cm mobile phase; ethanol), and the title optically active substance with a retention time of 14 minutes (64 mg; >99% ee) and the title optically active substance with a retention time of 16 minutes (58 mg; >97% ee) were obtained. The physical properties of the title optically active substance with a retention time of 14 minutes are as follows.
