Reaction Steps

To a mixture of 3-[3-(4-Methoxy-phenyl)-[1,2,4]oxadiazol-5-yl]-piperidine hydrochloride (0.320 g, 1.08 mmol) in THF (2.3 ml, 0.5M) was added Pyridine (0.3 ml, 3.78 mmol). The reaction mixture was cooled to 0° C. and 4-Fluoro-benzoyl chloride (0.172 g-0.87 mmol) was slowly added. The reaction was to go up to R.T and stirred for 24 h. The solution was concentrated and DCM was added following by HCl 1N. The aqueous phase was separated and organic phase was extracted twice with HCl 1N and twice with water, dried over Na2SO4, filtered and concentrated. The crude product was purified by flash chromatography (DCM/MeOH: 99/1) to afford 0.26 mg (66%) of {3-[3-(4-Methoxy-phenyl)-[1,2,4]oxadiazol-5-yl]-piperidin-1-yl}-phenyl-methanone as a white powder.
