실험 절차

tert-Butyl (3S,5R)-3-[({2-tert-butyl-4-[(3-methoxypropyl)amino]pyrimidin-5-yl}carbonyl)(2-methylpropyl)amino]-5-(1,4-dioxa-8-azaspiro[4.5]dec-8-ylcarbonyl)piperidine-1-carboxylate (72 mg) was dissolved in acetonitrile (8 ml), TFA (2 ml) was added and the mixture was stirred at room temperature for 3 hr. The reaction mixture was poured into 25% aqueous potassium carbonate solution at 0° C., and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to reversed-phase preparative HPLC, and fractions eluted with water-acetonitrile (9:1) to acetonitrile were collected. The mixture was basified (pH 10) with saturated aqueous potassium carbonate solution, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the object compound (29 mg).
