| titleOfInvention | A PROCEDURE FOR PREPARING 5-CIANO- (3,4'-BIPIRIDIN) -6 (1H) -ONA |
| abstract | PROCEDURE FOR OBTAINING 5-CYANE- (3,4 '' - BIRIPIDIN) -6- (1H) -ONE IN THE FORM OF A FREE BASE OR AS A CATIONIC SALT OF THE SAME. 4-PICILLIN IS REACTED WITH AT LEAST THREE MOLAR EQUIVALENTS OF AN INORGANIC ACID HALOGENIDE AND WITH AN EXCESS OF DIMETHYL FORMAMIDE. WATER IS INCORPORATED TO THE MIXTURE AND THE PH IS ADJUSTED TO A VALUE OF 8, WHICH PRECIPITATES THE CATIONIC SALT N- (O-DIMETHYLAMINO-2- (4-PYRIDINYL) -I-PORPENYLIDENE) -N-METHYLMETHANIMI-NIO, WHICH IS TREATED WITH AN EXCESS OF ALPHA-CYANOACETAMIDE AND WITH AT LEAST THREE MOLAR EQUIVALETS OF A BASE TO OBTAIN THE DESIRED COMPOUND. THROUGHOUT THE PROCESS, THE TEMPERATURE IS KEPT BELOW 30 C. APPLICATION AS AN INTERMEDIATE COMPOUND IN THE PREPARATION OF 3-AMINO-5- (4-PYRIDINYL) -2-1H) -PYRIDINONE. |
