Hydrochloric Acid → HCID 18770417, compound

Participants

Reaction Steps

Concentrated hydrochloric acid (0.050 ml; 0.60 mmol) was added to a solution in ethanol (5 ml) of 1,2-bis[4-[(E,E)-5-(3,4,5-trimethoxyphenyl)-2,4-pentadienoyl]-1-piperazinyl]ethane (128 mg; 0.19 mmol) synthesized in the above process 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 the title compound as a pale yellow crystalline powder.
