De her omhandlede alkylamid- og esterderivater adskiller sig fra de kendte forbindelser ved, at de kun har ét basisk 25 centrum (tertiær amin) i molekylet, og denne ændring i strukturen resulterer i forbindelser med en mere ønskelig hæmodynamisk profil.

Alkoxy-grupper med 1-6 carbonatomer er f.eks. methoxy, ethoxy, 5 propoxy og butoxy. Halogen henviser til halogenatomer, såsom chlor, brom, fluor og iod. Phenacetyl henviser til en usubstitueret phenylgruppe.
Stillingen af substituenten X i forhold til det punkt, hvor phenyl er tilknyttet, er ikke kritisk. Inden for ram-10 merne af den foreliggende opfindelse er således ortho-, meta- eller para-monosubstituerede phenylgrupper, hvor X står for en halogen-, trifluormethyl-, phenyl-, alkyl-eller alkoxysubstituent. En foretrukket udførelsesform for den foreliggende opfindelse er 2-chlor-substitueret phenyl, 15 hvis X er chlor.
Farmaceutisk acceptable syreadditionssalte afledes fra syrer, såsom saltsyre, hydrogeniodidsyre, hydrogen-bromidsyre, phosphorsyre, svovlsyre/ toluensulfonsyre, eddikesyre, maleinsyre og benzoesyre.
20 Forbindelser ifølge den foreliggende opfindelse er værdifulde på grund af deres evne til at inhibere ventriculær arrhythmia som vist ved det følgende forsøg.
Ventriculær arrhythmia fremkaldes med en 2-rtrins ligation af den forreste, nedadgående gren af den venstre 25 coronararterie i hver især af to eller flere ikke-r-be- døvede hunde. Forsøgsforbindelsen indgives intravenøst i doser på 5 mg/kg til en maksimumdosis på 20 mg/kg.
En forbindelse bedømmes som værende aktiv, hvis den frembringer en reduktion af ektopiske hjerteslag på mindst 25% 30 i en periode på mindst 10 minutter hos halvdelen eller flere af de afprøvede hunde. Den gennemsnitlige effektive mindstedosis bestemmes for hver aktiv forbindelse.
Anti-arrhytmiske midler, der er effektive hos mennesker, såsom guinidin, procainamid og "Norpace"®, 35 er aktive i dette forsøg.

De forbindelser, der viser sig at være aktive i en udstrækning på 75-100%'s reduktion af ventriculær arrhythmia eller et toksiske i ovennævnte forsøg ved 5 mg/kg afprøves ved indgivelse af en dosis på 1 mg/kg med mellemrum på 5 5 minutter. En forbindelse bedømmes som aktiv, hvis den frembringer en reduktion i ektopiske hjerteslag på mindst 25% i en periode på mindst 10 minutter hos halvdelen eller flere af de afprøvede hunde.

Forbindelserne ifølge den foreliggende opfindelse adskiller sig fra kendte forbindelser ved det faktum, at de er i besiddelse af en mere ønskelig hæmodynamisk 25 profil. Medens forbindelserne ifølge den foreliggende opfindelse undertrykker ventriculær arrythymia hos ikke--bedøvede hunde indenfor samme dosisområde som kendte forbindelser beskrevet i US patentskrift nr. 4.107.205, er de således i besiddelse af formindsket myocardialunder-r-3Q trykkende aktivitet som vist i tabel II. Denne reduktion af den negative inotropiske aktivitet er særlig gunstig ved det dysrhythmiske hjerte, hvor undertrykkelse af sammentrækkeligheden kan være særlig livstruende.

En opløsning af a-[2-bis-(1-methylethyl)-aminoethyl--2-chloracetonitril i THF behandles med 1 ækvivalent 20 frisk fremstillet LDA ved -78°C. Efter 10 minutter tilsættes 1 ækvivalent 2 M tris- (isopropoxyl-titanchlorid i hexan, og reaktionsblandingen får lov at opvarme til stuetemperatur. Til reaktionsblandingen sættes derefter 1 ækvivalent 2-chlorethylpyrrolidin-2-on i THFj og opløs-25 ningen omrøres i 1-6 timer. Efter at reaktionsblandingen er blevet hældt ud i en 2 N HCl-opløsning, vaskes den vandige fase med ether, før den gøres basisk med en natriumhydroxidopløsning.
