Procedure
To a stirred solution of ({3-[2-(tert-butoxycarbonyl-pyridin-4-yl-amino)-ethoxy]-5-chloro-benzoyl}-cyclobutyl-amino)-propionic acid (0.025 g) and HATU® (0.038 g) in DMF (1 ml) was added DIPEA (0.017 ml) followed by tert-butylamine (0.053 ml) after 10 min. The reaction mixture was stirred at room temperature for 18 h and then concentrated under reduced pressure. The residue was subjected to preparative hplc and the title compound (0.021 g) was obtained as a colourless gum by concentration of the required fraction under reduced pressure and drying by repetitive addition of acetonitrile and concentration under reduced pressure.
