Reaction Steps

A solution of sodium bis(trimethylsilyl)amide (36 mL, 1M) was diluted with THF (60 mL) and cooled to 0° C. 2-Fluoro-4-methylpyridine (2.0 g, 18 mmol) was then added and after 45 min. at 0° C. ethyl benzoate (3.24 g, 21 mmol) was added dropwise. Stirring was continued for 45 min. and the solution then poured into 2M HCl (100 mL) cooled to 0° C. After thorough mixing, the solution was basified to pH9 with 5M NaOH, and the product extracted into ether (3×30 mL). The ethereal layers were combined and washed with brine (1×30 mL), dried (MgSO4) and concentrated under reduced pressure. The residue was dissolved in a minimum of dichloromethane and precipitated by addition of pet. spirit. The solid was collected and washed with cold pet. spirit to afford the pure product as a pale brown solid (2.8 g, 72%).
