Fluoxastrobin may further be prepared as described in Scheme 3. Particularly, 4,6-dichloro-5-fluoropyrimidine (5) is reacted with 2-chlorophenol in an appropriate solvent and in the presence of a suitable base to give intermediate 4-chloro-6-(2-chlorophenoxy)-5-fluoropyrimidine (17) which is further reacted with (E)-(5,6-dihydro-1,4,2-dioxazin-3-yl)(2-hydroxyphenyl)methanone O-methyl oxime (13) to give fluoxastrobin.
