실험 절차

To a solution of N-(2-amino-2-methylcyclopentyl)-2-(2H-1,2,3-triazol-2-yl)benzamide hydrochloride (Intermediate 26; 287 mg, 1.01 mmol) in dry DMSO (3.4 ml) was added 2-chloro-5-(trifluoromethyl)pyrazine (CAS number 799557-87-2; 202 mg, 1.11 mmol) and DIPEA (527 μl, 3.02 mmol). The reaction was stirred at 140° C. for 1 hour and was then partitioned between ethyl acetate and water. The organics were washed with water, brine, filtered through a hydrophobic frit and concentrated in vacuo. This was purified by column chromatography (silica, 0-100% ethyl acetate/petrol then 0-20% methanol/ethyl acetate) and was then recrystallised from ethyl acetate to afford the title compound.
