Procedure

1-tert-Butyl 3-methyl (3R*,5S*)-5-[({2-tert-butyl-4-[(2-furylmethyl)amino]pyrimidin-5-yl}carbonyl)(isobutyl)amino]piperidine-1,3-dicarboxylate (250 mg) was dissolved in 2 M aqueous sodium hydroxide solution (1 ml) and methanol (2 ml), and the mixture was stirred at room temperature for 15 hr. The reaction mixture was concentrated under reduced pressure, and the residue was diluted with water. The mixture was adjusted to pH 3 with 1 M hydrochloric acid, and the precipitate was collected by filtration to give the object compound (205 mg) as a powder.
