Procedure
A solution 2-Chloro-nicotinonitrile (5.0 grams, 36.1 mmole), cesium carbonate (23.5 grams, 72.2 mmole) and 3-chlorophenol (4.65 grams, 36.1 mmole) in dimethylformamide (100 ml) was heated to 80° C. over night. The mixture was cooled and poured into 500 ml water and extracted with diethyl ether. The combined extracts were washed with water and brine, dried over MgSO4, filtered, and concentrated to a white solid (8.21 g). M.P. 88-90° C.; Anal. calcd. for C12H7N2OCl: C, 62.49; H, 3.06; N, 12.15. Found: C, 62.43; H, 3.00; N, 12.13.
