反応手順

A solution of (1S,2S)-1-N-methyl-1-N-[5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 23; 60 mg, 0.20 mmol), 3-(2H-1,2,3-triazol-2-yl)pyridine-2-carboxylic acid (CAS number 1252907-86-0; 40 mg, 0.21 mmol), EDC (58 mg, 0.30 mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol (41 mg, 0.30 mmol) and triethylamine (0.085 ml, 0.61 mmol) in DCM (1 ml) was stirred at room temperature over the weekend. The reaction was concentrated in vacuo and was then purified by column chromatography (basic silica, 20 to 100% ethyl acetate/petrol) followed by column chromatography (silica, 0 to 100% ethyl acetate/petrol) to afford the title compound.
