Reaction Steps

To a flask was added tert-butyl 2-(6-(1-methyl-1H-pyrazol-4-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl)hydrazinecarboxylate (0.152 g, 0.331 mmol, Preparation #O.1), HCl (4.0 M in 1,4-dioxane, 0.827 mL, 3.31 mmol) and 1,4-dioxane (5 mL). The mixture was heated to about 60° C. for about 1 h then stirred at rt overnight. The mixture was diluted with EtOAc (10 mL), washed with aqueous saturated NaHCO3, dried over anhydrous MgSO4 and concentrated in vacuo to give 2-hydrazinyl-6-(1-methyl-1H-pyrazol-4-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine (0.100 g, 84%): LC/MS (Table 2, Method c) Rt=1.43 min; MS m/z 360 (M+H)+.
