実験手順

3-Methyl-4-oxo-3,4-dihydroimidazo[5,1-d][1,2,3,5]tetrazine-8-carbothioamide (0.48 mmol) and 2,4′-dibromoacetophenone (0.48 mmol) were stirred in MeCN overnight at room temperature. A slight yellow solid persisted which was filtered off before the remaining mixture was purified by preparative thin layer chromatography, eluting with 10% MeCN/DCM, to give the title compound. Yield=81%. δH (DMSO-d6): 8.92 (1H, s), 8.39 (1H, s), 8.04 (2H, d, J=8.8), 7. (2H, d, J=8.8), 3.89 (3H, s).
