Procedure

1-tert-Butyl 3-methyl (3R*,5S*)-5-{[(2-tert-butyl-4-chloropyrimidin-5-yl)carbonyl](2-methylpropyl)amino}piperidine-1,3-dicarboxylate (2.46 g) and diisopropylethylamine (1.38 ml) were dissolved in N,N-dimethylformamide (50 ml), 3-methoxypropan-1-amine (990 μl) was added and the mixture was stirred at 80° C. for 30 min. The reaction mixture was concentrated under reduced pressure, saturated aqueous sodium hydrogen carbonate was added, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate and the solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and the fraction eluted with hexane to ethyl acetate-hexane (35:65) was concentrated under reduced pressure to give the object compound (2.47 g).
