Versuchsvorschrift

1-(Piperidin-4-yl)-7H-pyrrolo[3,2-e][1,2,3]triazolo[1,5-c]pyrimidine acetate (30.0 mg, 0.0992 mmol) obtained in Reference Synthetic Examplea 104 in N,N-dimethylformamide (1 mL) was stirred with 3,3,3-trifluoropropionic acid (14.0 μL, 0.161 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (48.0 mg, 0.248 mmol), 1-hydroxybenzotriazole (34.0 mg, 0.248 mmol) and triethylamine (43.0 μL, 0.310 mmol) at room temperature for 3 hours and then with water (1 mL) for another 1 day. After addition of water, the reaction mixture was extracted with ethyl acetate, and the organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=2/1 (v/v)) to give the title compound as a colorless solid (11.7 mg, yield 34%).
