실험 절차

6-Chloro-3-ethylthio-2-pyridinecarbonitrile (23.8 g) was mixed with 25.8 g of 4-benzoylphenol in the presence of 15.7 g of t-BuOK in 150 ml of THF and 30 ml DMSO. After reaction, the mixture was filtered leaving a solid residue from which 12.4 g of the desired 6-(4-benzoylphenoxy)-3-ethylthio-2-pyridinecarbonitrile (m.p. 88°-90° C.) was recovered. An additional 6.5 g of desired product was isolated from the filtrate by separation on a Water's Prep LC 500 instrument (using a 10% acetone in hexane eluant).
