Reaction Steps

A solution of 2-Chloro-nicotinic acid ethyl ester (2.07 grams, 11.2 mmole), Cesium carbonate (7.27 grams, 22.3 mmole) and 5-chloro-3-pyridinol (1.45 grams, 11.2 mmole) in dry dimethylformamide (40 ml) was stirred at 90° C. overnight. The suspension was cooled to room temperature, poured into water and extracted with diethyl ether. The combined organics were washed with water and brine, dried over MgSO4, and concentrated to a tan solid. Recrystalization from hexane gave a yellow solid (1.0 g). M.P. 65-69° C.; Anal. calcd. for C13H11ClN2O3: C, 56.03; H, 3.98; N, 10.05. Found: C, 56.14; H, 4.04; N, 10.16.
