Reaction Steps

A solution of (1S,2S)-1-N-[3-fluoro-5-(trifluoromethyl)pyridin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 34; 379 mg, 1.44 mmol), 3-(pyrimidin-2-yl)pyridine-2-carboxylic acid (CAS number 1228431-21-7; 290 mg, 1.44 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (34 mg, 0.250 mmol) (294 mg, 2.16 mmol), EDC (415 mg, 2.16 mmol) and triethylamine (0.604 ml, 4.32 mmol) in DCM (1 ml) was stirred at room temperature for 16 hours. The reaction was added partitioned between DCM and as saturated solution of sodium bicarbonate. The organics were filtered through a hydrophobic frit and loaded directly on to a cation/anion mixed mode cartridge, eluted with DCM and concentrated in vacuo. The resulting residue was purified by reverse phase chromatography (C18 silica, 0-100% water (0.1% ammonia)/acetonitrile) to afford the title compound.
