Participants

Reaction Steps

To a solution of tert-butyl (3R,5S)-3-amino-5-[({2-tert-butyl-4-[(furan-2-ylmethyl)amino]pyrimidin-5-yl}carbonyl)(2-methylpropyl)amino]piperidine-1-carboxylate (70 mg) in 1,2-dichloroethane (3 ml) were successively added triethylamine (55 μl) and acetic anhydride (35 μl), and the mixture was stirred at room temperature for 3 hr. The reaction mixture was acidified with 1 M hydrochloric acid, 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-methanol (50:50:0-85:0:15) was concentrated under reduced pressure to give the object compound (28.5 mg).
