4-Hydroxybenzaldehyde → HCID 12323413, compound
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Hydroxybenzaldehyde | HCID 126 | — |
| Reactant | Cyclopentanone | HCID 8452 | — |
| Product | HCID 12323413 | HCID 12323413 | — |
Reaction Steps
The procedure was similar to that in Example 4 by reacting 4-hydroxybenzaldehyde with the morpholine enamine of cyclopentanone to give 2-(E)-[(4-hydroxy) benzylidene]cyclopentanone. The melting point of this intermediate compound was determined to be 188°-190° C. A subsequent Mannich reaction yielded the 2-Dimethylaminomethyl-5-(E)-[(4-hydroxy) benzylidene] cyclopentanone hydrochloride. The melting point of the product was determined to be 174°-175° C.
