PURPOSE:To obtain the titled substance useful as an insecticide, by reacting an aniline derivative with a carboxylic acid or its reactive derivative. CONSTITUTION:A compound shown by the formula I (R2 and R3 are H, halogen, nitro, alkyl, alkenyl, cycloalkyl, alkylsulfonyl, etc., or R2 and R3 are bonded to form ring; X is O, S, methylene, sulfonyl, etc.) is reacted with a compound shown by the formula II (R1 is H, or lower alkyl) or its reactive derivative in a molar ratio of 1:1-10 at 50 deg.C- the boiling point of the reaction mixture for 1-50hr, to give a compound shown by the formula III. The reaction may be carried out in an inert solvent such as water, benzene, CCl4, etc. |
