Participants

Reaction Steps

A solution of (1S,2S)-1-N-[5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 14; 116 mg, 0.41 mmol), 2-(5-ethoxypyrimidin-2-yl)benzoic acid (Intermediate 47; 100 mg, 0.41 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (84 mg, 0.61 mmol), EDC (118 mg, 0.61 mmol) and triethylamine (0.171 ml, 1.23 mmol) in dry DCM (4 ml) was stirred at room temperature for 4 hours. The reaction was partitioned between DCM and water, filtered through a hydrophobic frit and concentrated in vacuo. The crude product was purified by reverse phase preparative HPLC (eluted with acetonitrile/water with 0.1% ammonia) and then by reverse phase preparative HPLC (eluted with acetonitrile/water containing 0.1% formic acid) to afford the title compound.
