Procedure

A solution 2-Chloro-nicotinic acid ethyl ester (5.0 grams, 27.0 mmole), cesium carbonate (2.96 grams, 67.5 mmole) and Benzo[1,3]dioxol-5-ol (4.19 grams, 29.7 mmole) in dimethylformamide (80 ml) was heated to 65° C. for 10 hours. The mixture was diluted with water and extracted with ethyl acetate. The combined extracts were washed with water and brine, dried over MgSO4, filtered, and concentrated to a solid (7.0 g). MW 287.275.
