    Abstract: THIS INVENTION RELATES TO A PROCESS FOR THE PREPARATION OF CHLORINATED QUINOLINES OF THE FORMULA

    4-CL,CL-QUINOLINE

    WHEREIN THE CHLORINE ATTACHED TO THE BENZENE NUCLEUS IS IN A POSITION SELECTED FROM THE GROUP CONSISTING OF THE 5, 6, 7 AND 8 POSITIONS. THE SAID PROCESS INVOLVES REACTING A 2, 3 OR 4-CHLOROANILINE WITH A COMPOUND SELECTED FROM THE GROUP CONSISTING OF B-PROPIOLACTONE AND A COMPOUND OF THE FORMULA

    CH2=CH-COOR

    WHEREIN R IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND LOWER ALKYL, CYCLIZING THE 3-(CHLOROANILINO)PROPIONIC ACID FORMED WITH POLYPHOSPHORIC ACID, CHLORINATING THE RESULTING 5, 6, 7 OR 8-CHLORO-4-OXO-1,2,3,4TETRAHYDROQUINOLINE WITH PHOSPHORUS OXYCHLORIDE AND RECOVERING SAID CHLORINATED QUINOLINE. THE DICHLOROQUINOLINES ARE KNOWN PRODUCTS USEFUL AS INTERMEDIATES IN THE PRODUCTION OF KNOWN COMPOUNDS HAVING THERAPEUTIC ACTIVITY.
