Abstract

PROCEDIMIENTO PARA LA OBTENCION DE DIAMINOPIRIDINAS Y DE SUS SALES DE ADICION DE ACIDO, DE FORMULA (I), EN LA QUE Q, R Y R'' SON HIDROGENO O ALQUILO INFERIOR; PY ES 4 - O 3-PIRIDINILO, CON 0, 1 O 2 SUSTITUYENTES ALQUILO INFERIOR; Y R1, Y R3 PUEDEN SER VARIOS TIPOS DE RADICALES. CONSISTE EN LA REACCION DE REDUCCION DE UN COMPUESTO 3-NITRO DE FORMULA (II), EN LA QUE Q, PY, R Y R3 TIENE EL MISMO SIGNIFICADO QUE EN LA FORMULA (I). LA REDUCCION SE LLEVA A CABO MEDIANTE HIDROGENACION CATALITICA, UTILIZANDO UN CATALIZADOR COMO PALADIO SOBRE CARBON AL 10 POR 100, NIQUEL RANEY O SIMILAR. TAMBIEN SE PUEDEN OBTENER LOS COMPUESTOS DE FORMULA (I), POR REACCION DE UN COMPUESTO DE FORMULA (III) CON AMONIACO O UNA AMINA PRIMARIA O SECUNDARIA, FORMULA EN LA QUE HAL ES CLORO, BROMO O YODO, Y Q, PY, R Y R3 SON LOS MISMOS QUE EN LA FORMULA (I).
