Reaction Steps

A solution of (R)—N-(piperidin-3-yl)-6-(pyrazolo[1,5-a]pyrazin-3-yl)pyrazin-2-amine (Preparation 30b, 0.23 g, 0.78 mmol), 3-[(2,5-dioxopyrrolidin-1-yl)oxy]-3-oxopropane nitrile (prepared as described in BE875054(A1), 0.17 g, 0.94 mmol)) and triethylamine (0.13 mL, 0.94 mmol) in methylene chloride (10 mL) was stirred overnight at ambient temperature. After evaporation of the solvent, the crude mixture was purified by flash chromatography (95:5 to 93:7 methylene chloride/methanol) to yield the title compound (0.158 g, 38%) as a pale yellow solid.
