Abstract
PURPOSE: To prepare the titled compound useful as an agent for controlling noxious weeds, in high yield and purity, by reacting a benzylamine derivative with a 2-halo-3,3-dimehylbutyric acid halide in the presence of an alkaline aqueous solution.
CONSTITUTION: The objective compound of formula III is prepared by reacting the benzylamine derivative of formulaI(R1, R2 and R3 are 1W4C lower alkyl; Y is methyl, etc; n is integer of 0W3) with the 2-halo-3,3-dimethylbutyric acid halide of formula II (X1 and X2 are Cl or Br) in the presence of an alkaline aqueous solution such as an NaOH solution, usually at 0W100°C.
EFFECT: Since the cyrstalline product can be separated only by filtering the reaction mixture after the completion of the reaction, the operation is extremely easy and the process is industrially advantageous.
