실험 절차

To 6-benzyl-1,7-dimethyl-N-piperidin-4-yl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridin-4-amine (10. mg, 0.027 mmol, from Example 206) in DCM (1.0 mL) was added acetyl chloride (2.3 μL, 0.032 mmol, Aldrich), followed by the addition of triethylamine (7.4 μL, 0.053 mmol). After 15 minutes, volatiles were removed in vacuo. The mixture was diluted with water and MeOH, and the product was isolated via preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (7.6 mg, 68%).
