反応手順

As further shown in Scheme 5, fluoxastrobin may be prepared by sequentially reacting 4,6-dichloro-5-fluoropyrimidine (5) with 2-chlorophenol that gives 4-chloro-6-(2-chlorophenoxy)-5-fluoropyrimidine (17) which on further reaction with (Z)-(5,6-dihydro-1,4,2-dioxazin-3-yl)(2-hydroxyphenyl)methanone O-methyl oxime (15) gives (Z)-fluoxastrobin, which under appropriate conditions may undergo isomerization to fluoxastrobin.
