Participants

Reaction Steps

Prepared according to the procedure for 2-(difluoromethyl)-N-[(1S,2S)-2-{[5-(trifluoromethyl)pyrazin-2-yl]amino}cyclopentyl]benzamide (Example 65) from (1S,2S)-1-N-[5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 14; 100 mg, 0.35 mmol) and 2-cyclopropyl-6-fluorobenzoic acid (CAS number 1603213-26-8; 64 mg, 0.35 mmol) except to this was added EDC (68 mg, 0.354 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (48 mg, 0.35 mmol) and triethylamine (0.1 ml, 0.71 mmol) and the reaction was stirred at room temperature for a further 1 hour. The reaction mixture was partitioned between DCM and water, filtered through a hydrophobic frit and concentrated in vacuo. The resulting residue was purified by reverse phase preparative HPLC (eluted with acetonitrile/water containing 0.1% formic acid) and then triturated with heptane/diethyl ether to afford the title compound.
