Pyridylpyrimidine derivative, production thereof and plant blight controlling agent containing said derivative as active ingredient

Abstract

Abstract NEW MATERIAL:A compound expressed by formula I [n is 0W5; R 1 represents lower alkyl, halogen atom., lower haloalkyl or lower alkoxy; R 2 and R 3 represent H or lower alkyl; R 4 represents H or lower alkyl; R 5 represents H, lower alkyl or halogen atom.; R 4 and R 5 may link with -(CH 2 ) m - to form cyclic structure; m is 3 or 4; R 6 represents H, straight-chain alkyl, lower alkoxy, lower alkenyloxy, etc.] and salts thereof. EXAMPLE: 2-(6-m-Chlorophenyl-2-pyridyl)-4-methylpyrimidine. USE: A controlling agent for plant blights. PREPARATION: A halopyrimidine derivative expressed by formula II (X represents halogen atom.) is brought into contact and reduced with hydrogen gas, for example in a solvent in the presence of a catalyst at ambient temperature W50°C for 0.5W3hr.
