실험 절차
5-Chloro-2-ethylthio-4-pyridinecarbonitrile (5.4 g) was mixed with 5.4 g of 3,4-dichlorophenol in the presence of 3.7 g of t-BuOK in 30 ml of THF and 30 ml of DMSO. The mixture was heated at boiling temperature for about 70 hours to give 3.2 g (36%) of the desired 5-(3,4-dichlorophenoxy)-2-ethylthio-4-pyridinecarbonitrile, m.p. 79°-81° C.
