Patent GB-761796-A (GB)
Title: New quinoline derivatives
Inventor: CARRINGTON HERBERT CLARE
IPC: C07D215/42
Filed: 1954-03-10
Abstract: The invention comprises quinoline derivatives of the general formula <FORM:0761796/IV(b)/1> wherein X is -NH-, -O-, -S- or -CH2-, R and R1 are hydrogen or alkyl and R11 is alkyl and their preparation by heating the corresponding bis - (4 - halogenoquinoline) compounds with an amine HNRR1.  The reaction may be conducted between 100 DEG and 200 DEG  C., conveniently in the presence of a solvent such as phenol, and in some cases conveniently under increased pressure.  In examples: (1) ammonia is blown into a melt of phenol and acetamide and 4 : 41 - dichloro - 6 : 61 - di (2 - methylquinolyl) amine is added.  The product is isolated as 4 : 41-diamino-6 : 61-di-(2-methylquinolyl) amine dihydrochloride from which the free base is then liberated; (2) 4 : 41-di(methylamino) - 6 : 61 - di - (2 - methylquinolyl) amine dihydrochloride and the corresponding free base are obtained from the appropriate di-chloro compound and methylamine hydrochloride in a melt of phenol and caustic potash as solvent; (3) 4 : 41 - diamino - 6 : 61 - di - (2 - methylquinolyl) ether dihydrochloride and the corresponding free base are obtained by the method of Example (1); (4) 4 : 41-diamino-6 : 61-di-(2-methylquinolyl) methane is similarly prepared; (5) 4 : 41 - diamino - 6 : 61 - di - (2 - methylquinolyl) sulphide is similarly prepared; (6) 4 : 41 - bis - (dimethylamino)-6 : 61 - di(2 - methylquinolyl) amine dihydrochloride and the corresponding free base are prepared by the method of Example (2).  Starting materials.  The bis-(4-halogenoquinoline) compounds may be prepared by the action of, for example, phosphorus oxychloride on the corresponding hydroxy compounds which themselves may be obtained by ring closure by heat of the condensation product of, for example, an acetoacetic ester with a compound <FORM:0761796/IV(b)/2> Specification 761,797 is referred to.

Kinematograph apparatus. - In a projector having means for bringing the film to rest, as described in the parent Specification, means are provided for automatically restarting the feed of the film after a predetermined time. As shown, a shaft 1 has a finger 4 rigidly attached to it, and a spring 7, connected to the finger and to the bearing boss 3, normally holds the shaft in a definite position. A socket 14 having an arm 5 is mounted on the shaft 1 so as to be slidable but not rotatable thereon, and is pressed away from the finger 4 by a spring 6. A second shaft 9 is driven by gearing from the projector mechanism and carries a triangular screw thread 8 and a disc 11 having a grooved stud 10. When the film is brought to rest, the finger 4 is rotated by the lever described in the parent Specification, either by contact therewith or through a mechanical or electrical connection. The arm 5, which is normally out of contact with the screw thread 8, is thus brought into contact with it, and, as the shaft 9 continues to rotate, is caused to travel towards the finger 4 and disc 11. When the arm reaches the disc it is engaged by the stud 10 and rotated back to the normal position, thus also rotating the finger 4 and the lever to their normal positions and causing the feed movement to be restarted. The spring 6 then returns the arm 5 to its normal position.
