Procedure

tert-Butyl (3S,5R)-3-[({2-tert-butyl-4-[(3-methoxypropyl)amino]pyrimidin-5-yl}carbonyl)(2-methylpropyl)amino]-5-[methoxy(methyl)carbamoyl]piperidine-1-carboxylate (75 mg) was dissolved in tetrahydrofuran (10 ml), 1 M methylmagnesium bromide in THF solution (1.3 ml) was added at 0° C., and the mixture was stirred at room temperature for 10 hr. Saturated aqueous ammonium chloride solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with 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 (0:1-1:1) was concentrated under reduced pressure to give the object compound (38 mg).
