실험 절차

After dissolving 120 mg of t-butyl 4-{[(4-{4-[(anilinocarbonyl)amino]-3-chlorophenoxy}-2-pyridyl)amino]carbonyl}-1-piperidine carboxylate in 5 ml of trifluoroacetic acid, the solution was stirred at room temperature for 5 minutes. Bicarbonate water and 5N aqueous sodium hydroxide were added and extraction was performed with ethyl acetate. The extract was washed with saline and dried over sodium sulfate. The drying agent was filtered off, and the solvent was distilled off under reduced pressure. After adding 5 ml of tetrahydrofuran, 26 mg of acetic acid, 92 mg of sodium triacetoxyborohydride and 0.5 ml of formaldehyde (37% in water) to the residue, the mixture was stirred at room temperature for 10 minutes. Bicarbonate water and 5N aqueous sodium hydroxide were added to the reaction solution, and extraction was performed with ethyl acetate. The extract was washed with saline and then passed through a glass filter coated with NH type silica gel. The silica gel was washed thoroughly with ethyl acetate, the ethyl acetate layers were combined and subjected to distillation under reduced pressure, and the residue was solidified with ethyl acetate and hexane to obtain 80 mg of a colorless powder.
