Reaction Steps

5-(3,5-Dichloro-benzoyl)-5,6-dihydro-cyclopenta[b]thiophen-4-one (1.5 g, 4.8 mmol), hydrazine monohydrate (0.35 mL, 7.2 mmol), glacial acetic acid (0.8 mL) and ethanol (15 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-(3,5-Dichloro-phenyl)-4,7-dihydro-1-thia-4,5-diaza-cyclopenta[a]pentalene (1.33 g, 4.3 mmol) as yellow solid in 90% yield.
