Versuchsvorschrift
2-Chloro-5-ethylthio-4-pyridinecarbonitrile (4.0 g) was reacted with 3.6 g of 3,4-dichlorophenol in the presence of 2.6 g of t-BuOK in 40 ml of THF and 4 ml of DMSO. 5.5 g (84.6%) of the desired, 2-(3,4-dichlorophenoxy)-5-ethylthio-4-pyridinecarbonitrile was recovered, m.p. 68°-69° C.
