Synthesis and Various Biological Properties of 3-(4-Benzylpiperizino)-1-(4-Ethoxyphenyl)-1-Alkyl(Aryl)-2-Phenylpropan-1-OL Dihydrochlorides

Resumo

Aminomethylation of 1-(4-ethoxyphenyl)-2-phenylethanone yielded 3-(4-benzylpiperazin-1-yl)-1-(4-ethoxyphenyl)-2-phenylpropan-1-one. Reduction of this compound with lithium aluminum hydride produced 3-(4-benzylpiperazin-1-yl)-1-(4-ethoxyphenyl)-2-phenylpropan-1-one, and interaction of this with Grignard reagents produced 3-(4-benzylpiperazinyl)-1-(4-ethoxyphenyl)-1-alkyl(aryl)-2-phenylpropan-1-ones. Some of the dihydrochlorides of the resulting compounds were found to have anti-inflammatory, analgesic, and peripheral n-cholinolytic activity.
