Abstract

PURPOSE: The titled compound useful as a herbicide through one-step reaction, by chlorinating a hydroxypyrazine derivative in the presence of dimethylformamide to give a chloropyrazine derivative, an intermediate, followed by aminating the intermediate without its isolation.
CONSTITUTION: A hydroxypyrazine derivative shown by the formula I (R1 is phenyl, furyl, or thienyl) is chlorinated with thionyl chloride in the presence of dimethylformamide preferably 85W130°C to give a chloropyrazine derivative shown by the formula II, Which is not isolated and reacted with an amine shown by the formula III (R2 and R3 are H, lower alkyl, lower alkenyl, lower alkynyl, etc., or R2 and R3 form heterocyclic ring having 3W7 members) under cooling conditions preferably at room or lower temperatures to give a compound shown by the formula IV. An amount of dimethylformamide is preferably 1W5wt% based on the compound shown by the formula I.
