Preparation and Physico-Chemical Properties of Alkyl Esters of [(2-Hydroxy 3-diphenyl—methylpiperazinyl)propoxy] Carbanilic Acids
Příprava a fyzikálně chemické vlastnosti alkylesterů kyseliny 2-, 3-, 4-(2-hydroxy-3-[(4--difenylmethyl)piperazin-1-yl] propoxy) fenylkarbamové
Práce se věnuje syntéze a studiu některých fyzikálně-chemických vlastností skupiny látek, potenciálníchantagonistů beta-adrenergních receptorů. Látky jsou hydrochloridy derivátů aryloxyaminopropanolu,kde bázickou část tvoří difenylmethylpiperazin a modifikována je aromatická částalkylestery (methyl až butyl) kyseliny karbamové v polohách 2-, 3-, 4-. Zastoupení prvků bylopotvrzeno elementární analýzou. Látky byly charakterizovány teplotou tání IČ a UV spektry. Bylastanovena jejich rozpustnost a povrchová aktivita. Pomocí TLC byla sledována čistota připravenýchlátek.

Overview
The paper is devoted to the synthesis and study of some physico-chemical properties of a group ofsubstances – potential antagonists of beta-adrenergic receptors. The substances are derivatives ofaryloxyaminopropanol, where the basic part consists of diphenylmethylpiperazine and the aromaticpart is modified with alkyl esters (methyl to butyl) of carbamic acid in positions 2-, 3-, 4-. Therepresentation of the elements was confirmed by elemental analysis. The substances were characterizedby melting point, IR and UV spectra. Their solubility and surface acitivity were determined.The purity of prepared substances was examined by means of TLC.
Key words:
preparation – aryloxyaminopropanol – surface tension – TLC
