Reaction Steps

A mixture of N-[(1S,2S)-2-aminocyclopentyl]-2-(2H-1,2,3-triazol-2-yl)benzamide hydrochloride (Intermediate 4; 75 mg, 0.24 mmol), 2-bromo-5-(trifluoromethoxy)pyridine (CAS number 888327-36-4; 59 mg, 0.24 mmol), BINAP (15 mg, 0.024 mmol), tris(dibenzylideneacetone)dipalladium(0) (11 mg, 0.012 mmol) and sodium tert-butoxide (33 mg, 0.34 mmol) in dry toluene (2.4 ml) was sealed, evacuated and purged with nitrogen and heated at 110° C. for 17 hours. The reaction was partitioned between ethyl acetate and water, washing with water, brine, filtered through a hydrophobic frit and concentrated in vacuo. The residue was purified by column chromatography (silica, 0-100% ethyl acetate/petrol) to afford the title compound.
