| abstract |
THIS INVENTION REFERS TO: (1) A COMPOUND REPRESENTED BY FORMULA (V), ITS TAUTOMERO AND A MIXTURE OF THE SAME; (2) A PROCEDURE TO PRODUCE THE COMPOSITE REPRESENTED BY THE FORMULA ABOVE MENTIONED (V), ITS TAUTOMERO OR A MIXTURE OF THE SAME, THAT UNDERSTANDS THE REACTION OF N-VINYLPIPERIDONE REPRESENTED BY THE FORMULA (I) WITH A NICOTINATE REPRESENTED BY (II), WHERE R REPRESENTS A LOW RENT GROUP, IN THE PRESENCE OF A SODIUM ALCOXIDE; (3) A PROCEDURE TO PRODUCE A PIRIDINE DERIVATIVE REPRESENTED BY THE FORMULA (III), WHICH INCLUDES THE PRODUCTION OF THE COMPOSITE REPRESENTED BY THE FORMULA (V), ITS TAUTOMERO OR A MIXTURE OF THE SAME THROUGH THE PROCEDURE DESCRIBED IN THE PREVIOUS POINT (PREVIOUS 2), ALREADY TREAT THE COMPOUND OBTAINED WITH AN ACID; AND (4) A PROCEDURE TO PRODUCE A PIRIDINE DERIVATIVE REPRESENTED BY FORMULA (IV), IN WHICH TREATMENT WITH AN ACID AS DESCRIBED IN THE PREVIOUS POINT (3) IS FOLLOWED BY ANOTHER TREATMENT WITH A BASE. Thus, THE PRESENT INVENTION PROVIDES INDUSTRIAL PROCEDURES TO PRODUCE PIRIDINE DERIVATIVES REPRESENTED BY FORMULA (III) AND (IV) IN A SAFE, ECONOMIC, EASY AND EFFECTIVE FORM WITHOUT USING ANY HAZARDOUS REAGENTS. |
