Hydrochloric Acid → HCID 18770433, compound

Participants

Reaction Steps

Concentrated hydrochloric acid (0.050 ml; 0.60 mmol) was added to a solution of 1,4-bis[[4-[(E,E)-5-(3,4,5-trimethylphenyl)-2,4-pentadienoyl]-1-piperazinyl]-methyl]benzene (100 mg; 0.14 mmol) in ethanol (5 ml) and the reaction mixture was concentrated under reduced pressure. After a process of adding ethanol (10 ml) to the residue and concentrating the mixture under reduced pressure was performed twice, the resultant concentrated residue was recrystallized from methanol-diethyl ether to obtain 69 mg (yield: 47%) of the title compound as a colorless crystalline powder.
