Embodiment

[0095] The present invention is illustrated in detail by the following Production Examples, Formulation Examples, and Test Examples.

[0096] First, production examples of the compounds of the present invention will be described.

[0097] Production example

[0098]

[0099] Under a nitrogen atmosphere, to 0.50 g of 5-benzyl-3-furylmethanol, 0.62 g of (1R)-cis-2,2-dimethyl-3-((E)-3-ethoxy -2-fluoro-3-oxo-1-propenyl)cyclopropanecarboxylic acid, 0.1g of 4-(dimethylamino)pyridine and 7ml of dichloromethane were added to a mixture of 0.60g of N,N-dicyclohexyl carbon diimine, and the mixture was stirred at room temperature for 3 hours. Then, the reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography to obtain 0.69 g of 5-benzyl-3-furylmethyl(1R)-cis-2,2-dimethyl-3-((E)-3- Ethoxy-2-fluoro-3-oxo-1-propenyl)cyclopropanecarboxylate (hereinafter, referred to as the present com...
