A mixture of give 2-(4-fluorobenzoyl)-3-hydroxypyridine (2.2 g, 11.3 mmol), ethyl bromoacetate (1.6 ml, 14.15 mmol) and potassium carbonate (4.34 g, 31.4 mmol) in acetone (40 ml) was heated at reflux. After 3 h, the reaction was cooled to room temperature, filtered and concentrated in vacuo to give ethyl 2-[2-(4-fluorobenzoyl)pyridin-3-yloxy]acetate (3.5 g) which was used in the next step without further purification.
