| Reactant | 9-Acetyl-6,9-dihydroxy-7,8,9,10-tetrahydrotetracene-5,12-dione | HCID 13051574 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | HCID 13293015 | HCID 13293015 | 92.2% |
Reaction Steps
Reaction of 9-acetyl-6,9-dihydroxy-5,7,8,9,10,12-hexahydronaphthacene-5,12-dione (690 mg) with pyrrolidone hydrotribromide (1.15 g) was effected in tetrahydrofuran (70 ml) at room temperature for 40 hours. After removing insoluble matters by filtration, the solvent was distilled off under reduced pressure to give yellow crystals (785 mg, 92%) of 9-bromoacetyl-6,9-dihydroxy-5,7,8,9,10,12-hexahydronaphthacene-5,12-dione. M.P., 179°-180° C.
