Participants

Reaction Steps

A solution of (1S,2S)-1-N-[5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 14; 14 mg, 0.05 mmol), 2-fluoro-6-methoxybenzoic acid (CAS number 137654-21-8; 8.5 mg, 0.05 mmol), TOTU (20 mg, 0.06 mmol) and 4-methylmorpholine (0.008 ml, 0.075 mmol) in DMF (0.25 ml) was stirred at room temperature for 1 hour. The reaction was then diluted with methanol and concentrated in vacuo. The resulting residue was purified by reverse phase preparative HPLC (eluted with acetonitrile/water with 0.1% ammonia) to afford the title compound.
