PROCEDURE
实验过程
Methyl (E)-2-{2-[6-chloropyrimidin-4-yloxy]phenyl}-3-methoxyacrylate (98.4 g at 97.7% strength; prepared as described in WO 92/08703) was added to MIBK (210 g) and water (38.3 g) and heated to 45-50° C. 2-Cyanophenol (40.1 g), potassium carbonate (63.4 g) and DABCO (0.51 g) were added and the temperature was raised to 80° C. and held for 5.5 hours. Water (316 g) was added and agitation continued for 30 minutes before settling and separating the aqueous layer. Analysis of the MIBK solution revealed a 91.8% yield of methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate (azoxystrobin).
