Procedure

{[(3S,5R)-1-(tert-Butoxycarbonyl)-5-(morpholin-4-ylcarbonyl)piperidin-3-yl](2-methylpropyl)amino}(oxo)acetic acid (10.3 g), HOBt (4.13 g) and WSC.HCl (6.28 g) were dissolved in DMF (50 ml), N-(4-methoxybutyl)benzene-1,2-diamine (4.67 g) and diisopropylethylamine (11.3 ml) were added, and the mixture was stirred at room temperature for 15 hr and at 60° C. for 2 hr. The reaction mixture was concentrated, and the residue was diluted with aqueous sodium bicarbonate, 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 a fraction eluted with ethyl acetate was concentrated under reduced pressure to give the object product (9.11 g).
