Reaction Steps

A solution of (1S,2S)-1-N-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 33; 327 mg, 1.03 mmol), 3-(pyrimidin-2-yl)pyridine-2-carboxylic acid (CAS number 1228431-21-7; 250 mg, 1.24 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (211 mg, 1.55 mmol), EDC (297 mg, 1.55 mmol) and triethylamine (0.432 ml, 3.10 mmol) in DCM (4 ml) was stirred at room temperature for 18 hours. The reaction was partitioned between DCM (10 ml) and water (10 ml), filtered through a hydrophobic frit and concentrated in vacuo. The resulting residue was purified by column chromatography (0-100% ethyl acetate/petrol) and was then by reverse phase chromatography (C18 silica, 5-95% water (0.05% ammonia)/acetonitrile) to afford the title compound.
