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-cyclopropyl-5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 48; 105 mg, 0.33 mmol) and 3-(pyrimidin-2-yl)pyridine-2-carboxylic acid (CAS number 1228431-21-7; 79 mg, 0.39 mmol) except after work-up, the organics were loaded directly on to a cation/anion mixed mode cartridge, eluted with DCM, then methanol and 2M ammonia in methanol and concentrated in vacuo. The resulting residue was purified by column chromatography (silica, 0-100% ethyl acetate/petrol) to afford the title compound.
