Exemple. - a) Chlorure de l'acide phényl-l cyclopentane carboxylique-1.
Dans un ballon muni d'une ampoule à robinet et d'un réfrigérant ascendant surmonté d'une garde à chlorure de calcium reliée à des absorbeurs, on introduit 150 g d'acide phényl-1 cyclopentane carboxylique-1 et 1120 cm3 de benzène sec.
On chauffe à reflux jusqu'à dissolution complète de l'acide puis' on introduit lentement 150 cm3 de chlorure de thionyle purifié. Dès l'addition d'une petite quantité de chlorure de thionyle, une vive réaction se déclenche avec dé- gagement d'anhydride sulfureux. Après addition complète on chauffe à reflux jusqu'à cessation du dégagement gazeux..
On chasse alors le benzène par distillation sous pression réduite; il reste dans le ballon 160 g d'un liquide constitué par le chlorure brut de l'acide phényl-cyclopentane carboxylique qui titre 85 à 90% en produit pur. Par lavage à l'éther on peut le purifier davantage et l'amener à 98%; mais il est utilisable tel quel pour la préparation de l'ester (I). b) Ester phényl-1 cyclopentane carboxylique-1 ou

On chauffe à reflux pendant 4 heures, on isole le chlorhydrate de l'ester, on le dissout dans le minimum d'eau et on alcalinise franchement au carbonate de sodium. L'ester précipite; on l'essore sur buchner, le lave à plusieurs reprises à l'eau et on le sèche.

The following example illustrates the preparation of the new derivatives according to the invention.
<Desc / Clms Page number 3>
Example. - a) Phenyl-1 cyclopentane carboxylic acid chloride-1.
150 g of 1-phenyl-1-cyclopentane-carboxylic acid and 1120 cm3 of dry benzene are introduced into a flask fitted with a stopcock and an ascending condenser surmounted by a calcium chloride guard connected to absorbers. .
The mixture is heated to reflux until the acid has completely dissolved, then 150 cm3 of purified thionyl chloride are introduced slowly. As soon as a small quantity of thionyl chloride is added, a vigorous reaction is set off with the evolution of sulfur dioxide. After complete addition, the mixture is heated under reflux until the evolution of gas ceases.
The benzene is then removed by distillation under reduced pressure; 160 g of a liquid consisting of the crude chloride of the phenyl-cyclopentane carboxylic acid which has a content of 85 to 90% of pure product remains in the flask. By washing with ether it can be further purified and brought to 98%; but it can be used as it is for the preparation of the ester (I). b) Phenyl-1 cyclopentane carboxylic ester-1 or
EMI3.1
4-morpho1y1 ethanol
In a flask surmounted by a condenser with a calcium chloride guard tube, 130 g of morpholyl ethanol are dissolved in 260 cm 3 of anhydrous benzene and 260 g of phenyl cyclopentane carboxylic acid chloride are added.
The mixture is refluxed for 4 hours, the hydrochloride is isolated from the ester, dissolved in the minimum amount of water and frankly basified with sodium carbonate. The ester precipitates; it is drained on a buchner, washed several times with water and dried.
EMI3.2
200 g of morpholyl-ethyl ester of 1-phenyl-cyclopentane carboxylic acid are thus obtained, which after purification melts at 40 -41,
