Hydrochloric Acid → (E)-3-(4-{(E)-3-[2-(4-methyl-piperazin-1-ylmethyl)-phenyl]-3-oxo-propenyl}-phenyl)-acrylic acid bis-hydrochloride

Participants

Reaction Steps

A mixture of 4-formylcinnamic acid (189 mg, 1.077 mmol), 1-[2-(4-methyl-piperazin-1-ylmethyl)-phenyl]-ethanone (obtained as described in Preparation 11, 250 mg, 1.077 mmol) and 1.7 M KOH (1.26 ml) in EtOH (5 ml) and H2O (5 ml) was stirred at room temperature overnight and then acidified with 10% HCl. The resulting precipitate was filtered to give 350 mg of (E)-3-(4-{(E)-3-[2-(4-methyl-piperazin-1-ylmethyl)-phenyl]-3-oxo-propenyl}-phenyl)-acrylic acid bis-hydrochloride.
