Reaction Steps

1-tert-Butyl 3-methyl (3R*,5S*)-5-[({2-tert-butyl-4-[(3-methoxypropyl)amino]pyrimidin-5-yl}carbonyl)(2-methylpropyl)amino]piperidine-1,3-dicarboxylate (304 mg) was dissolved in tetrahydrofuran-methanol (1:2, 12 ml), 2 M aqueous sodium hydroxide solution (1.35 ml) was added and the mixture was stirred for 2 hr. The reaction mixture was concentrated under reduced pressure, and diluted with saturated aqueous ammonium chloride solution, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the object compound (287 mg).
