实验步骤: 26 ml of 2-methylacetophenone(0.2M), 32 ml of formamide and 7.5 ml of formic acid were mixed and reacted at 160° C. for 5 hours while distilling water off. The resultant was cooled to room temperature and extracted from ethyl ether. The extract was washed with water, concentrated under a reduced pressure, added with 20 ml of concentrated hydrochloric acid and heated under reflux for an hour. The reaction solution was cooled to room temperature, washed with ethyl ether and neutralized with aqueous NaOH solution. After extracting the resultant with ethyl ether, the extract was dried over anhydrous sodium sulfate and concentrated under a reduced pressure, to give 16.9 g of the title compound. reacted at 160° C. for 5 hours while distilling water off extracted from ethyl ether The extract was washed with water concentrated under a reduced pressure added with 20 ml of concentrated hydrochloric acid heated under reflux for an hour The reaction solution was cooled to room temperature washed with ethyl ether and neutralized with aqueous NaOH solution After extracting the resultant with ethyl ether the extract was dried over anhydrous sodium sulfate concentrated under a reduced pressure

实验步骤: IPEA (0.5 mL), EDC (128 mg) and HOBT (90.4 mg) were added to a solution of 5-chloro-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzylidene)valeric acid trifluoroacetate (100 mg) and 1-o-tolylethylamine (60 mg) in DMF (5 mL), and the reaction solution was stirred at room temperature for 1 hour. Water and ethyl acetate were added to the reaction solution and the organic layer was partitioned. The resulting organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (Carrier: Chromatorex™ NH, elution solvent: heptane-ethyl acetate system->ethyl acetate-methanol system) to obtain 5-chloro-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzylidene)valeric acid (1-o-tolylethyl)amide. Sodium hydride (containing mineral oil at 40%, 50 mg) was added to a solution of the resulting 5-chloro-2-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzylidene)valeric acid (1-o-tolylethyl.)amide in DMF (4 mL), and the reaction solution was stirred at room temperature for 10 minutes. Water and ethyl acetate were added to the reaction solution and the organic layer was partitioned. The resulting organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (Carrier: Chromatorex™ NH, elution solvent: heptane-ethyl acetate system->ethyl acetate-methanol system) to obtain 60 mg of the title compound as a racemate. The compound (10 mg) was fractionated using CHIRALPAK™ AD-H manufactured by Daicel Chemical Industries, Ltd. (2 cm×25 cm: mobile phase: hexane:ethanol=7:3) to obtain the title optically active substance with a retention time of 39 minutes (4.4 mg; >99% ee) and the title optically active substance with a retention time of 48 minutes (4.4 mg; >99% ee). The physical properties of the compounds are as follows. the organic layer was partitioned The resulting organic layer was dried over anhydrous magnesium sulfate the solvent was evaporated under reduced pressure The residue was purified by silica gel column chromatography (Carrier: Chromatorex™ NH, elution solvent: heptane-ethyl acetate system->ethyl acetate-methanol system)
