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; 510 mg, 1.96 mmol) and 2-(2H-1,2,3-triazol-2-yl)benzoic acid (CAS number 1001401-62-2; 445 mg, 2.35 mmol) except this was then partitioned between water (20 ml) and DCM (10 ml). The organics were washed with water (2×20 ml) and brine (20 ml), filtered through a hydrophobic frit and concentrated in vacuo. The residue was purified by column chromatography (silica, 0-100% ethyl acetate/petrol) followed by a trituration with diethyl ether and recrystallised from IPA/water to afford the title compound.
