3-Amino-5,5-dimethyl-2-cyclohexen-1-one → 9-(3,4-difluorophenyl)-3,4,6,7,9,10-hexahydro-3,3,6,6-tetramethyl-1,8(2H,5H)-acridinedione
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 3-Amino-5,5-dimethyl-2-cyclohexen-1-one | HCID 136680 | — |
| Reactant | 3,4-Difluorobenzaldehyde | HCID 588088 | — |
| Product | 9-(3,4-difluorophenyl)-3,4,6,7,9,10-hexahydro-3,3,6,6-tetramethyl-1,8(2H,5H)-acridinedione | HCID 22117846 | — |
Reaction Steps
Reaction of 3-amino-5,5-dimethyl-2-cyclohexen-1-one with 3,4-difluorobenzaldehyde in an analogous manner to that described in Example 1 gave 9-(3,4-difluorophenyl)-3,4,6,7,9,10-hexahydro-3,3,6,6-tetramethyl-1,8(2H,5H)-acridinedione. Crystallization from absolute ethanol/water gave a pale yellow crystalline solid of melting point 270° C. (decomposition).
