Reaction Steps

To a solution of (S)-tert-butyl N-(1-(pyrrolo[1,2-a]pyrazin-1-yl)pyrrolidin-3-yl)carbamate (0.88 g, 2.9 mmol, 1 eq) in 3.6 mL of dioxane was added a solution of 4.0 M HCl in dioxane (3.6 mL, 14.5 mmol, 5 eq). After heating for 1 h at 60° C., the mixture was concentrated to afford (S)-1-(pyrrolo[1,2-a]pyrazin-1-yl)pyrrolidin-3-amine (0.79 g, 2.9 mmol, 100%).
