Reaction Steps

A solution of 1-N-[3-fluoro-5-(trifluoromethyl)pyridin-2-yl]-1-methylcyclopentane-1,2-diamine (Intermediate 28; 57 mg, 0.21 mmol), 3-(2H-1,2,3-triazol-2-yl)pyridine-2-carboxylic acid (CAS number 1252907-86-0; 51 mg, 0.27 mmol), EDC (51 mg, 0.27 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (36 mg, 0.27 mmol) and triethylamine (0.086 ml, 0.62 mmol) in DCM (3 ml) was stirred at room temperature for 18 hours. The reaction was then diluted with DCM (20 ml) and a saturated solution of sodium bicarbonate (10 ml), filtered through a hydrophobic frit and concentrated in vacuo. The residue was purified by column chromatography (silica, 0-100% ethyl acetate/petrol) to afford the title compound.
