A solution of (1S,2S)-1-methyl-1-N-[5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine (Intermediate 25; 50 mg, 0.192 mmol), 3-(pyrimidin-2-yl)pyridine-2-carboxylic acid (CAS number 1228431-21-7; 46 mg, 0.231 mmol), triethylamine (80 ul, 0.576 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (34 mg, 0.250 mmol) and EDC (48 mg, 0.250 mmol) in DCM (5 ml) was stirred at room temperature for 18 hours. The reaction was partitioned between DCM (20 ml) and a saturated solution of sodium bicarbonate (10 ml). The aqueous layer was further extracted with DCM (20 ml) and the combined organics were filtered through a hydrophobic frit and concentrated in vacuo. The resulting residue was purified by column chromatography (silica, 0-100% ethyl acetate/petrol) to afford the title compound.
