Participants

Reaction Steps

A microwave vial was charged with N-(2-amino-4,4-difluorocyclopentyl)-2-(2H-1,2,3-triazol-2-yl)benzamide hydrochloride (Intermediate 42; 65 mg, 0.19 mmol), 2-chloro-5-(trifluoromethyl)pyrazine (CAS number 799557-87-2; 38 mg, 0.21 mmol) and DIPEA (99 μl, 0.57 mmol) in dry DMSO (630 μl). The reaction was subjected to microwave irradiation at 140° C. for 30 minutes. The reaction was partitioned between ethyl acetate and water. The organics were washed with water and brine, dried over magnesium sulfate, filtered and concentrated in vacuo. The crude material was purified by column chromatography (basic silica, 0-100% ethyl acetate/petrol) to afford the title compound.
