Procedure

To a solution of N-[(1S,2S)-2-amino-4,4-difluorocyclopentyl]-2-methylpropane-2-sulfonamide (1.03 g, 4.02 mmol) in dry DCM (13.4 ml) was added 2-(2H-1,2,3-triazol-2-yl)benzoic acid (CAS number 1001401-62-2; 0.91 g, 4.82 mmol), EDC (2.31 g, 12.06 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (1.64 g, 12.06 mmol) and DIPEA (2.11 ml, 12.06 mmol). The reaction was stirred at room temperature overnight then partitioned between ethyl acetate and water. The organics were washed with water and brine, dried over sodium sulfate, filtered and concentrated in vacuo. The crude material was purified by column chromatography (silica, 30-80% ethyl acetate/petrol) to afford the title compound.
