Procedure

(3R,5S)-1-(tert-Butoxycarbonyl)-5-[({2-tert-butyl-4-[(3-methoxypropyl)amino]pyrimidin-5-yl}carbonyl)(isobutyl)amino]piperidine-3-carboxylic acid (110 mg), morpholine (52 μl) and diisopropylethylamine (140 μl) were dissolved in DMF (8 ml), BOP reagent (265 mg) was added and the mixture was stirred at room temperature for 1.5 hr. The reaction mixture was diluted with saturated aqueous sodium hydrogen carbonate, 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 purified by silica gel column chromatography, and the fraction eluted with ethyl acetate-hexane (1:9) to ethyl acetate was concentrated under reduced pressure to give the object compound (105 mg).
