Reaction Steps

A solution of 2-(5-methyl-1,3,4-oxadiazol-2-yl)benzoic acid (CAS number 898289-64-0; 82 mg, 0.40 mmol), (1S,2S)-1-methyl-1-N-[5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine (Intermediate 25; 80 mg, 0.31 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (54 mg, 0.40 mmol), EDC (77 mg, 0.40 mmol) and triethylamine (0.13 ml, 0.92 mmol) in DCM (3 ml) was stirred at room temperature for 72 hours. The reaction was diluted with DCM and washed with a saturated solution of sodium bicarbonate, passing through a hydrophobic frit and concentrated in vacuo. The crude product was purified by reverse phase chromatography (C18 silica, 5-100% acetonitrile/water with 0.05% ammonia) to afford the title compound.
