NEW MATERIAL:N-substituted benzanilide derivatives of formulaI:(R 1 is methyl, or ethyl group; R 2 is alkyl or alkoxy group). n EXAMPLE: 4-t-Butyl-N-ethyl-2'-methylbenzanilide. n USE: Fungicides effective against piricularia oryzae (blast) of rice plants without damage to harvests. Usable without care. n PROCESS: For example, compounds of formula II are reacted with alkyl halides of formula R 1 X (X is galogen) in the presence of an alcoholate, e.g. sodium methylate, etc. or an alkali hydride, e.g. sodium hydride, etc. in a solvent, e.g. benzine, etc. to give the objective N-substituted benzamilide derivatives of formulaI. n COPYRIGHT: (C)1979,JPO&Japio |
