Versuchsvorschrift
(6-(5-Methoxy-1-methyl-1H-indol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl)methanamine (0.095 g, 0.22 mmol, Example #20, Step G) in ethyl formate (4.4 mL, 54.0 mmol) was heated at about 60° C. in an oil bath for about 45 min. The mixture was cooled and evaporated to give N-((6-(5-methoxy-1-methyl-1H-indol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl)methyl)formamide (0.10 g, 100%): LC/MS (Table 2, Method a) Rt=2.65 min; MS m/z: 466 (M+H)+.
