실험 절차

5-(3-Bromo-benzoyl)-5,6-dihydro-cyclopenta[b]thiophen-4-one (2.5 g, 8.2 mmol), hydrazine monohydrate (0.6 mL, 12 mmol), glacial acetic acid (1.5 mL) and ethanol (30 mL) were heated at 100° C. under nitrogen for 4 hr. The mixture was cooled to 25° C. and concentrated under reduced pressure to give a solid which was recrystallized from ethanol to provide the corresponding 6-(3-Bromo-phenyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (0.8 g, 2.5 mmol) as white solid in 30% yield.
