Reaction Steps

To a mixture of 3-(2-{[4-chloro-3-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-benzoyl]-methyl-amino}-phenoxy)-propionic acid 11-4 (50 mg, 0.10 mmol) and (2-amino-ethyl)-carbamic acid tert-butyl ester (51.5 mg, 0.54 mmol) in DMF (500 μL), EDCl (22 mg, 0.12 mmol), HOBt (16 mg, 0.12 mmol) and DIPEA (34 μl, 0.19 mmol) were added. The mixture was stirred for 48 hrs at rt, diluted with MeOH (500 μL) and purified by prep HPLC to afford {2-[3-(2-{[4-chloro-3-(4-cyano-6-trifluoromethyl-pyridin-3-yl)-benzoyl]-methyl-amino}-phenoxy)-propionylamino]-ethyl}-carbamic acid tert-butyl ester. After treatment with 50% TFA in DCM (1 mL) for 2 hrs, followed by concentration in vacuo, N-{2-[2-(2-amino-ethylcarbamoyl)-ethoxy]-phenyl}-4-chloro-3-(4-cyano-trifluoromethyl-pyridin-3-yl)-N-methyl-benzamide 53-1 was obtained. MS [M+H]+546.1; tR=5.66 min (method 2).
