intermediates of formula-4, and formula-5;
(b) reacting the mixture of azoxystrobin intermediates of formula-4, and formula-5 with
methanesulfonic acid or p-toluenesulfonic acid to obtain methyl (E)-2-{2-[6-chloropyrimidin-4-
yloxy]phenyl}-3-methoxyacrylate of formula-5; and
(c) coupling of 2-cyanophenol with methyl (E)-2-{2-[6-chloropyrimidin-4-yloxy]phenyl}-3-
methoxyacrylate of formula-5 to obtain the azoxystrobin of formula-1.

2. The process as claimed in claim 1, the catalyst used in stage (a) is selected from a group consisting
of 4-methylmorpholine, 1,4-dimethylpiperazine, 2,2,6,6-tetramethylpiperidine, 1-
methylpiperidine, and 2,2'-oxybis (N, N-dimethylethan-1-amine) and the reaction medium used
in stage (a) includes inorganic base selected from potassium carbonate or sodium carbonate and
the solvent used in stage (a) selected from toluene or ethylene dichloride.
3. The process as claimed in claim 1, the mixture of the azoxystrobin intermediates comprise methyl
2-[2-(6-chloropyrimidin-4-yloxy) phenyl]-3,3-dimethoxypropionate of formula-4 and methyl
(E)-2-{2-[6-chloropyrimidin-4-yloxy] phenyl}-3-methoxyacrylate of formula-5.

4. The process as claimed in claim 1, reaction medium used in stage (b) includes acetic anhydride
or propionic anhydride and the solvent used in stage (b) selected from toluene or ethylene
dichloride.
5. The process as claimed in claim 1, stage (c) is carried out in presence of the catalyst bis[2-(N,Ndimethylamino)ethyl] ether and the reaction medium used in stage (c) includes potassium
carbonate and dimethyl formamide.
6. A process for the preparation of Azoxystrobin of formula-1, comprising:
(a) reacting (E)-3-(methoxy methylene) benzofuran-2(3H)-one of formula-2 with sodium methoxide
and 4,6-dichloropyrimidine in presence of a catalyst to obtain the mixture of azoxystrobin
intermediates of formula-4, and formula-5;
(b) coupling of 2-cyanophenol with the mixture of azoxystrobin intermediates of formula-4, and
formula-5 to obtain the mixture of variants of azoxystrobin of formula-7, and formula-1; and
(c) reacting the mixture of variants of azoxystrobin of formula-7, and formula-1 with
methanesulfonic acid or p-toluenesulfonic acid to isolate the pure azoxystrobin of formula-1.

7. The process as claimed in claim 6, the catalyst used in stage (a) is selected from a group consisting
of 4-methylmorpholine, 1,4-dimethylpiperazine, 2,2,6,6-tetramethylpiperidine, 1-
methylpiperidine, and 2,2'-oxybis (N, N-dimethylethan-1-amine) and the reaction medium used
in stage (a) includes an inorganic base selected from potassium carbonate or sodium carbonate
and the solvent used in stage (a) selected from toluene or ethylene dichloride.

8. The process as claimed in claim 6, the mixture of azoxystrobin intermediates comprise methyl 2-
[2-(6-chloropyrimidin-4-yloxy) phenyl]-3,3-dimethoxypropionate of formula-4 and methyl (E)-
2-{2-[6-chloropyrimidin-4-yloxy] phenyl}-3-methoxyacrylate formula-5.
9. The process as claimed in claim 6, the catalyst used in stage (b) is bis[2-(N,Ndimethylamino)ethyl] ether and the reaction medium used in stage (b) includes potassium
carbonate and dimethyl formamide.
10. The process as claimed in claim 6, the reaction medium used in stage (c) includes acetic anhydride
or propionic anhydride and the solvent used in stage (c) selected from toluene or ethylene
dichloride.
