Reaction Steps
A mixture of 4.0 g (0.02 mole) of 3-chloro-5-(trifluoromethyl)-2-pyridinol, 2.6 g (0.022 mole) of monobromoacetonitrile, and 4.0 g of potassium carbonate in 40 ml of dimethyl sulfoxide was prepared and stirred at ambient temperature for 3 hours. Water was then added and the light brown solid that formed was separated by filtration and dried to obtain 2.3 g (45 percent of theory) of the title compound: melting point, 84°-85° C. This product had infrared and nmr spectra compatible with the assigned structure.
