To a stirred solution of 3-[2-(tert-butoxycarbonyl-pyridin-4-yl-amino)-ethoxy]-5-chloro-benzoic acid (0.100 g), TBTU (0.080 g) and HOBt (0.034 g) in DMF (3 ml) was added DIPEA (0.087 ml) followed by 3-(cyclopentylamino)propionitrile (0.035 g) after 15 min. The reaction mixture was stirred at room temperature for 18 h and then concentrated under reduced pressure. The residue was washed with water and extracted with ethyl acetate. The organic layer was dried with brine and MgSO4, filtered and concentrated to give the title compound (0.190 g) as a brown oil.
