Reaction Conditions

Reaction Steps

A mixture of diethyl 2-(3-fluoropyridin-2-yl)malonate (2.68 g, 10.5 mmol), sodium chloride (0.675 g, 11.6 mmol) and water (0.378 mL, 21.0 mmol) in DMSO (15 mL) was heated at 145° C. for 4.5 h. The mixture was cooled, diluted with EtOAc and washed sequentially with water and brine. The organic phase was dried and concentrated to provide ethyl 2-(3-fluoropyridin-2-yl)acetate as a pale colored oil (1.90 g, 99% yield) which was used without further purification. Mass spectrum m/z 184 (M+H)+.
