Embodiment

[0863] Next, the present invention is described more specifically with reference to Examples, but the present invention is not limited to the Examples.

[0864] Reference Example 1: N-[1-((6-chloropyridin-3-yl)methyl)pyridin-2(1H)-ylidene]-2,2,2-trifluoroacetamide (compound P212)

[0865] (1) 25 g (270 mmol) of 2-aminopyridine was dissolved in 200 mL of anhydrous dichloromethane, 41 mL (30 g, 300 mmol) of triethylamine was added, and the mixture was cooled to 0°C. 38 mL (57 g, 270 mmol) of anhydrous trifluoroacetic acid was added dropwise over 15 minutes, and the resulting mixture was stirred at room temperature for 2 hours. After the reaction was completed, the reaction solution was poured into about 100 mL of ice water, and the mixture was stirred for 10 minutes. The mixture was moved to a separatory funnel for liquid separation, and the organic layer was washed twice with 150 mL of water and twice with 150 mL of 1% aqueous HCl, dried over anhydrous magnesium sulfate, and c...

Abstract

Provided is a nitrogen-containing heterocyclic derivative having a 2-imino group, which is represented by the following Formula (I). [Chemical Formula 1] [in the formula, Ar represents a phenyl groupwhich may be substituted, a 5- to 6-membered heterocycle which may be substituted, or a 4- to 10-membered heterocycloalkyl group, A represents a heterocycle having a 5- to 10-membered unsaturated bondincluding one or more nitrogen atoms, and has an imino group substituted with an R group at a position adjacent to the nitrogen atom present on the cycle, Y represents a hydrogen atom, a halogen atom, a hydroxyl group, a C1 to C6 alkyl group which may be substituted with a halogen atom, a C1 to C6 alkyloxy group which may be substituted with a halogen atom, a cyano group, or a nitro group, and Rrepresents any one of groups represented by the following Formulae (a) to (e), (y) or (z).

Description

[0001] This application is a divisional application of PCT application PCT / JP2013 / 056055, which was submitted on February 27, 2013 and has an invention title of "Nitrogen-containing heterocyclic derivatives having 2-imino groups and pest control agents containing the same". The date when the above-mentioned PCT application entered the national phase in China was September 10, 2014, and the application number was 201380013407.1. [Technical field] [0002] The present invention relates to a nitrogen-containing heterocyclic derivative having a 2-imino group and a new pest control agent using the same. [Background technique] [0003] Although many pest control agents have been discovered so far, new drugs are still needed due to problems such as reduced drug sensitivity, long-term effects, and safety during use. [0004] Especially for rice cultivation in East and Southeast Asia, damage caused by planthoppers that have developed resistance to major insecticides containing neonic...
