Procedure

A solution of (1S,2S)-1-N-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 33; 100 mg, 0.32 mmol), 3-(2H-1,2,3-triazol-2-yl)pyridine-2-carboxylic acid (CAS number 1252907-86-0; 66 mg, 0.35 mmol), EDC (91 mg, 0.47 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (65 mg, 0.47 mmol) and triethylamine (0.132 ml, 0.95 mmol) in DCM (1 ml) was stirred at room temperature overnight. The reaction was partitioned between water (5 ml) and DCM (5 ml), 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.
