Versuchsvorschrift

(6-(5-Methoxy-1-methyl-1H-indol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl)methanol (0.63 g, 1.4 mmol) in DCM (10 mL) was treated with SOCl2 (0.115 mL, 1.58 mmol) and stirred for about 15 min at ambient temperature. The solvents were evaporated then sodium azide (0.280 g, 4.31 mmol) and DMF (5 mL) were added. The mixture was then stirred at ambient temperature overnight. The solvent was evaporated and the residue was partitioned between water (30 mL) and EtOAc (25 mL). The aqueous layer was washed with EtOAc (15 mL) then the combined organic solutions were dried over anhydrous MgSO4, filtered, and concentrated to give 2-(azidomethyl)-6-(5-methoxy-1-methyl-1H-indol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine (0.58 g, 87%): LC/MS (Table 2, Method a) Rt=3.42 min; MS m/z: 464 (M+H)+.
