Reaction Conditions

Reaction Steps

To a solution of ethyl 2-(3-fluorophenyl)acetate (I8) (10.1 g, 55.0 mmol) in CCl4 (250 mL), NBS (9.70 g, 55.0 mmol) is added and the mixture refluxed for 2 hours at 80° C. (LC-MS monitoring: complete conversion). The solvent is evaporated and the resulting crude is dissolved in DCM and purified by filtration on a silica bed in order to obtain 7.80 g of (I9) as a colorless oil (54% yield).
