Reaction Steps

A solution of N-(2-amino-2-methylcyclopentyl)-2-(2H-1,2,3-triazol-2-yl)benzamide hydrochloride (Intermediate 26; 150 mg, 0.47 mmol), 2-bromo-5-(trifluoromethoxy)pyridine (CAS number 888327-36-4; 118 mg, 0.49 mmol), BINAP (29 mg, 0.047 mmol), tris(dibenzylideneacetone)dipalladium(0) (21.34 mg, 0.023 mmol) and sodium tert-butoxide (63 mg, 0.65 mmol) in dry toluene (1.6 ml) was sealed, evacuated and purged with nitrogen. The reaction was heated at 140° C. for 17 hours and was then partitioned between ethyl acetate and water, washing with water, brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified by column chromatography (silica, 0-70% ethyl acetate/petrol) to afford the title compound.
