Reaction Steps

To a solution of (1S,2S)-1-N-[5-(trifluoromethyl)pyridin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 1; 1.09 g, 3.87 mmol) in DCM (13 ml) was added 2-fluoro-6-(2H-1,2,3-triazol-2-yl)benzoic acid (CAS number 1186050-58-7; 0.802 g, 3.87 mmol), DIPEA (2.027 ml, 11.61 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (0.579 g, 4.26 mmol) and EDC (0.816 g, 4.26 mmol). The reaction was stirred at room temperature for 17 hours and was then partitioned between DCM and a saturated solution of sodium bicarbonate, filtered through a hydrophobic fit and concentrated in vacuo. The residue was purified by column chromatography (basic silica, 0-100% ethyl acetate/petrol) and recrystallised from IPA to afford the title compound.
