실험 절차

tert-Butyl (3R*,5S*)-3-(aminocarbonyl)-5-[({2-tert-butyl-4-[(2-furylmethyl)amino]pyrimidin-5-yl}carbonyl)(isobutyl)amino]piperidine-1-carboxylate (469 mg) was dissolved in pyridine (5 ml), trifluoroacetic anhydride (0.25 ml) was added under ice-cooling, and the mixture was stirred at room temperature for 11 hr. The reaction mixture was concentrated under reduced pressure, and the residue was diluted with ethyl acetate. The solution was washed successively with 1 M hydrochloric acid and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and the fraction eluted with ethyl acetate-hexane (5:95-80:20) was concentrated under reduced pressure to give the object compound (402 mg).
