A stirred solution of 3-(4-bromophenyl)-1 ,4-diazaspiro[4.4]non-3-en-2-one (D3) (770 mg2,4-dimethyl-1 H-imidazole (379 mg, 3.94 mmol) and copper bis(2,2,6,6-tetramethyl- 3,5-heptanedionate) (337 mg, 0.788 mmol) in DMF (3 ml) at room temperature, under argon was treated with potassium tert-butoxide (1179 mg, 10.51 mmol). After stirring at room temperature for 5 min, the mixture was heated to 12O0C and this temperature was maintained for 16 h. Further batches of the imidazole (379 mg) and copper bis(2, 2,6,6- tetramethyl-3,5-heptanedionate) (337 mg) were added and heating was continued for 7 days. The reaction mixture was cooled and diluted with saturated aqueous sodium bicarbonate solution (100 ml) and ethyl acetate (100 ml). After mixing, the mixture was filtered through Kieselghur. The ethyl acetate layer was separated and the aqueous phase re-extracted with ethyl acetate (50 ml). The combined organics were dried (MgSO4) and evaporated. The residue was applied in MeOH to an SCX column (10 g). After washing with MeOH the product was eluted with 2M NH3-MeOH. Evaporation afforded a brown gum. Chromatography (1 Og isolute column, 0-2% MeOH-DCM) afforded, after solvent removal, material (250 mg) consistent with presence of 2 isomers in approx 9:1 ratio with the major component subsequently confirmed (by 1H NMR nOe studies at the final product stage) as the title compound.Mass Spectrum (Electrospray LC/MS): Found 309 (MH+). Ci8H20N4O requires 308. Ret. time 1.02 min

The synthetic route of 930-62-1 has been constantly updated, and we look forward to future research findings.
