Das erfindungsgemässe Verfahren erfolgt in der Weise, dass man die entsprechende 5,5-Dialkylacri- dan-10-carbonsäure und einen Aminoalkohol oder deren funktionelle Derivate miteinander verestert.
Am zweckmässigsten geht man dabei so vor, dass man den basischen Alkohol, gegebenenfalls als Me- tallalkoholat oder in Gegenwart einer anorganischen oder organischen Base, mit dem betreffenden 5,5-Di- al'kylacridan-10-carbonsäurehal'ogenid umsetzt, wobei die Reaktion beispielsweise nach folgendem Formel schema verläuft:

R stellt dabei einen zweiwertigen organischen Rest dar; R1, R2, R3 und R4 bedeuten gleiche oder ver schiedene, geradlinige oder verzweigte aliphatische Reste, von denen R3 und R4 auch zu einem hetero- zyklischen Ring, gegebenenfalls unter Einschluss eines weiteren Heteroatoms;
zusammengeschlossen sein können, und X1, X2, X3 und X4 können unter sich gleich oder verschieden sein und Wasserstoff, Halo gen oder andere Substituenten wie beispielsweise Al kyl-, Trifluoralkyl-, Aryl-, Carboxy-, Carbäthoxy-, Nitro-, Amino-,
Thio- oder Alkylth'io-Gruppen dar stellen.

Dann. gibt man dem Ge misch 5,5 g des als Ausgangsmaterial dienenden Säurechlorids zu und erhitzt wertere 12 Stunden lang zum Rückfluss, worauf man filtriert und das Filtrat mit 50 cm3 0,
5n HCl ausschüttelt. Aus dem durch mehrmaliges Ausschütteln mit Äther gereinigten wäss- rigen Auszug erhält man durch Zusatz der äquiVaden- ten Menge Natronlauge, Eitraktion mit Äther und Eindampfen des Extraktes den 5,5-Dimethylacridan- 10-carbonsäure-(2-dimethylaminoäthyl)-ester als freie Base in Form eines hellen Öls.
Durch Neutralisation mit alkoholischer HCl bildet sich daraus ein, wasser lösliches Chlorhydrat, das aus Alkohol-Äther (2: 1) umkristallisiert werden kann. Smp. 206-207 C. Aus beute 80-90 %.
