Reaction Steps

To a solution of methyl 1-{2-oxo-2-[5-(trifluoromethyl)pyridin-2-yl]ethyl}-1H-pyrrole-2-carboxylate (85 mg, 0.26 mmol) in 1,4-dioxane (20 mL) was added ethane-1,2-diamine (0.65 mL, 9.7 mmol). The solution was heated at reflux. After 4 days the reaction was complete (monitored by LCMS). The mixture was then concentrated in vacuo to give an oily solid. The material was purified by flash chromatography (Biotage SP4, 12 g cartridge, gradient CH2Cl2 1 CV, 0-10% MeOH in CH2Cl2 10 CV) to give 10a-[5-(trifluoromethyl)pyridin-2-yl]-2,3,10,10a-tetrahydro-1H,5H-imidazo[1,2-a]pyrrolo[1,2-d]pyrazin-5-one (70 mg, yield: 85%). ESI-MI m/z [M+H]+ 323.0.
