Sodium Carbonate → HCID 11522081, compound

Participants

Reaction Steps

4-[2-methoxy-3-(trifluoromethyl)phenyl]-1-propylpiperidine (0.18 g, 0.6 mmol) and pyridine hydrochloride (2 g) was heated to 190° C. and stirred for 2 h. Aqueous sodium carbonate (10%, 50 ml) and ethyl acetate (50 ml) was added and the phases were separated. The aqueous phase was extracted with ethyl acetate (2×50 ml) and the combined organic phase was dried (MgSO4) and evaporated under reduced pressure to give an oil. Purification by flash column chromatography (ethyl acetate/methanol, 1:1) gave the title compound: 0.17 g (98%). The amine was converted to the hydrochloric acid salt and recrystallized from ethanol/diethyl ether: M.p. 218-220° C. MS m/z (relative intensity, 70 eV) 287 (M+, 10), 259 (14), 258 (bp), 238 (15), 195 (19).
