Versuchsvorschrift

To a solution of 1,7-dimethyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyridine (10.0 mg, 0.0537 mmol, from Example 2, Step 5) in DMF (1.5 mL) was added sodium hydride (0.0065 g, 0.16 mmol, 60% in mineral oil). After stirring for 10 minutes, 1-(bromomethyl)-2-fluorobenzene (0.010 g, 0.054 mmol, Aldrich) was added. After stirring for 45 minutes, the reaction was quenched with water, diluted with MeCN and filtered, then was purified by preparative HPLC-MS (Waters XBridge C18, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH) (7 mg, 40%).
