Reaction Steps

To a solution consisting of 5-(2-chloroethyl)-3-(2-fluorophenyl)-6,7-dihydro-1,2-benzisoxazol-4(5H)-one (2.5 g) and DMF (85 ml) was added anhydrous potassium carbonate (0.6 g), diisopropylethyl amine (2.2 ml), 4-(4-fluorobenzoyl)piperidine (2.3 g) and potassium iodide (70 mg) at room temperature with stirring. The flask was flushed with nitrogen and warmed to 80° C. for 19 hours. Upon cooling to room temperature, water and ethyl acetate were added to the reaction mixture. The layers were separated and the aqueous phase was extracted 3 times with ethyl acetate. The combined organic layers were washed with brine and dried (MgSO4). Filtration and concentration gave the crude product.
