Reaction Steps

To a solution 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) in NMP (1.0 ml) was added DIPEA (160 mg, 1.24 mmol) and 2,5-dichloropyrazine (CAS number 19745-07-4; 92 mg, 0.62 mmol). The resulting reaction mixture was stirred and heated under microwave irradiation at 180° C. for 15 minutes. Upon completion, the reaction mixture was 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.
