Reaction Steps

A microwave vial was charged with N-[(1S,2S)-2-aminocyclopentyl]-5-methyl-2-(2H-1,2,3-triazol-2-yl)benzamide hydrochloride (Intermediate 7; 450 mg, 1.40 mmol), 2-chloro-5-(trifluoromethyl)pyrazine (CAS number 799557-87-2; 306 mg, 1.68 mmol) and DIPEA (733 μl, 4.20 mmol) in dry DMSO (4.7 ml). The reaction was subjected to microwave irradiation at 140° C. for 2 hours and then partitioned between ethyl acetate and water, washed with water, brine and concentrated in vacuo. The crude product was then purified by column chromatography (basic silica, 0-100% ethyl acetate/petrol) to give a cream solid which was then recrystallised from a mixture of ethyl acetate and pentane to afford the title compound.
