NEW MATERIAL: A compd. represented by formula I {A is N or; CR5; R1, R2 and R5 are each H, halogen, formul, CN, alkyl, alkenyl, alkynyl, cycloalkyl, alkoxy, aryloxy, alkylthio or NH2; and R is a group represented by formula II [R3 is H, alkyl, a heterocyclic group or aryl; and R4 is COR6 (R6 is H, halogen, OH or alkoxy), OR7 (R7 is a heterocycle) or a group represented by formula III (R9 and R10 are H or alkyl)}.
EXAMPLE: Methyl-2-(4,6-dimethylpyrimidin-2-yl)oxy-3-methylbutanoate.
USE: A herbicide.
PROCESS: For example, a compd. represented by formula IV (L is a leavable group) and a compd. represented by formula V are reacted pref. under basic conditions in an inert org. solvent to obtain the compd. represented by formula I (R is the group represented by formula II).
