Reaction Steps

A mixture of N-[(1S,2S)-2-aminocyclopentyl]-5-methyl-2-(2H-1,2,3-triazol-2-yl)benzamide hydrochloride (Intermediate 7; 100 mg, 0.31 mmol), toluene (1 ml), BINAP (19 mg, 0.03 mmol), cesium carbonate (404 mg, 0.12 mmol) and 2-chloro-5-ethylpyrimidine (CAS number 111196-81-7; 48 mg, 0.34 mmol) was purged with nitrogen gas for 5 minutes before tris(dibenzylideneacetone)dipalladium(0) (14 mg, 0.02 mmol) was added. The reaction mixture was stirred at 100° C. for 15 hours and upon cooling poured into water (3 ml) and extracted with ethyl acetate (3×10 ml). The combined organics were dried over sodium sulfate and concentrated in vacuo. The crude product was purified by reverse phase preparative HPLC (eluted with acetonitrile/water containing 0.1% ammonia) to afford the title compound.
