Pyrrolidine → HCID 54085301, compound

Participants

Reaction Steps

To a stirred solution of 4-({3-[2-(tert-butoxycarbonyl-pyridin-4-yl-amino)-ethoxy]-5-chloro-benzoyl}-(2-fluoro-phenyl)-amino)-butyric acid (0.025 g), TBTU (0.028 g) and HOBt (0.012 g) in DMF (1 ml) was added DIPEA (0.015 ml) followed by pyrrolidine (0.007 ml) after 10 min. The reaction mixture was stirred at room temperature for 16 h and then concentrated under reduced pressure. The residue was subjected to preparative hplc and the title compound (0.025 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.
