Procedure

Prepared according to the procedure for N-[(1S,2S)-2-methyl-2-{[5-(trifluoromethyl)pyrazin-2-yl]amino}cyclopentyl]-3-(2H-1,2,3-triazol-2-yl)pyridine-2-carboxamide (Example 77) from (1S,2S)-1-methyl-1-N-[5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine (Intermediate 25; 63 mg, 0.24 mmol) and 2,6-difluorobenzoic acid (CAS number 385-00-2; 46 mg, 0.29 mmol) except this was purified by column chromatography (silica, 0-20% ethyl acetate/petrol) followed by reverse phase chromatography (C18 silica, 0-100% water (with 0.05% ammonia)/acetonitrile) to afford the title compound.
