実験手順

A mixture of 6-benzyl-1,7-dimethyl-N-piperidin-4-yl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridin-4-amine (7.0 mg, 0.019 mmol, from Example 206) and acetaldehyde (5.2 μL, 0.093 mmol, Aldrich) in DCM (2.4 mL) was treated with Na(OAc)3BH (5.2 mg, 0.024 mmol, Aldrich). After 8 minutes, the solvent was removed in vacuo, and the product was purified via preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (2.0 mg, 26%).
