5-Fluoro-2-(pyrimidin-2-yl)benzoic acid → 5-Fluoro-N-[(1S,2S)-2-{[3-fluoro-5-(trifluoromethyl)pyridin-2-yl]amino}cyclopentyl]-2-(pyrimidin-2-yl)benzamide

Participants

Reaction Steps

Prepared according to the procedure for 2-(5-Ethoxypyrimidin-2-yl)-N-[(1S,2S)-2-{[5-(trifluoromethyl)pyrazin-2-yl]amino}cyclopentyl]benzamide (Example 135) from (1S,2S)-1-N-[3-fluoro-5-(trifluoromethyl)pyridin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 34: 200 mg, 0.76 mmol) and 5-fluoro-2-(pyrimidin-2-yl)benzoic acid (CAS number 1293284-57-7; 166 mg, 0.76 mmol) except after the reaction was complete it was concentrated in vacuo and the residue was purified by reverse phase column chromatography (C18 silica, 0-100% water (0.05% ammonia)/methanol), then by column chromatography (silica, 0-50% ethyl acetate/petrol) and then triturated with DCM/petrol to afford the title compound.
