Versuchsvorschrift

4-(1H-Pyrazol-4-yl)-1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridine (50 mg, 0.0002 mol) (see, Example 231, Step 1) was dissolved in DMF (2 mL, 0.02 mol) and cooled at 0° C. This solution was treated with sodium hydride (7.0 mg, 0.00029 mol) (60% in oil) and stirred for 15 min. The mixture was then treated with 2-bromopentane (40 mg, 0.0002 mol) and was stirred for 5 h. The reaction was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over MgSO4, filtered and concentrated to give the crude product 4-[1-(1-methylbutyl)-1H-pyrazol-4-yl]-1-[2-(trimethylsilyl)ethoxy]methyl-1H-pyrrolo[2,3-b]pyridine as an oil, LC/MS (M+H)+: 286.
