実験手順
DBU (0.656 mL, 4.35 mmol) was added to a solution of 3-(1,3-dimethyl-2,4-dioxo-2,3,4,6-tetrahydro-1H-pyrrolo[3,4-d]pyrimidin-5-yl)benzonitrile (Example 9 Step 4) (1.22 g, 4.35 mmol) and methyl acrylate (0.392 mL, 4.35 mmol) in acetonitrile (15 mL). The mixture was stirred at room temperature for 4 days. Further portions of methyl acrylate (0.392 mL, 4.35 mmol) and DBU (0.656 mL, 4.35 mmol) were added as required to allow the reaction to run to completion. The reaction was quenched with saturated NH4Cl(aq) and extracted with DCM (2×). The combined organic extracts were passed through a hydrophobic frit and evaporated under vacuum. Purification by chromatography on silica, eluting with 20-100% EtOAc/hexane afforded a crude material which was triturated with DCM/diethyl ether/hexane to afford the title compound.
