Versuchsvorschrift

1-tert-Butyl 3-methyl (3R,5S)-5-[({2-tert-butyl-4-[(3-methoxypropyl)amino]pyrimidin-5-yl}carbonyl)(isobutyl)amino]piperidine-1,3-dicarboxylate (1.08 g) was dissolved in methanol (25 ml) and THF (12 ml), 2 M aqueous sodium hydroxide solution (4.79 ml) was added and the mixture was stirred at room temperature for 2 hr. The reaction mixture was concentrated under reduced pressure, the residue was diluted with saturated aqueous ammonium chloride 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 (1.05 g).
