実験手順
To a solution of 1-tert-butyloxycarbonyl-4-(4-amino-3-methylphenyloxy)piperidine hydrochloride (0.7 g) in methylene chloride (10 ml) were added triethylamine (0.62 g) and decanoyl chloride (0.39 g) with ice-cooling and the mixture was stirred at room temperature for 1 hour. Aqueous saturated solution of sodium dicarbonate was added to the reaction mixture and the organic layer was separated. The aqueous layer was further extracted with methylene chloride (50 ml×2) and the combined organic layer was dried over sodium sulfate and concentrated under reduced pressure. To the solidified residue was added trifluoroacetic acid (5 ml) and the mixture was stirred at room temperature for 30 minutes. The reaction mixture was concentrated under reduced pressure, the resulting residue was dissolved in ethanol and conc. hydrochloric acid (0.20 ml) was added thereto. The resulting solution was concentrated under reduced pressure and the residue was washed with hexane to obtain 4-(4-decanoylamino-3-methylphenyloxy)piperidine hydrochloride (0.93 g) as white crystals, m.p. 177°-195° C.
