Hydrochloric Acid → 1,3-Bis[4-[4-(3,4,5-trimethoxyphenyl)benzoyl]-1-piperazinyl]propane dihydrochloride

Participants

Reaction Steps

Concentrated hydrochloric acid (0.015 ml; 0.18 mmol) was added to a solution of 1,3-bis[4-[4-(3,4,5-trimethoxyphenyl)benzoyl]-1-piperazinyl]propane (43 mg; 0.050 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 methanoldiethyl ether to obtain the title compound as a colorless crystalline powder.
