To a solution of methyl 1-[2-(4-hydroxyphenyl)-2-oxoethyl]-1H-pyrrole-2-carboxylate (200 mg, 0.77 mmol) in 1,4-dioxane (40 mL) was added ethane-1,2-diamine (1 mL, 15 mmol), after 48 h extra ethane-1,2-diamine (1 mL, 15 mmol) was added and the mixture heated for 48 additional hours. After that time 90% of the starting material was converted into the above product. The resulting mixture was then concentrated in vacuo to give a residue that was purified by flash chromatography (Biotage SP4, 12 g cartridge, gradient 0-10% MeOH in CH2Cl2) to give 10a-(4-hydroxyphenyl)-2,3,10,10a-tetrahydro-1H,5H-imidazo[1,2-a]pyrrolo[1,2-d]pyrazin-5-one (180 mg, yield: 86%). ESI-MI m/z [M+H]+ 270.1.
