    摘要: A process for preparing diaminopyridines of the formula ##STR1## where one of the two radicals X.sup.1 and X.sup.2 is hydrogen, C.sub.1 -C.sub.4 -alkyl, halogen or nitro and the other is cyano,R.sup.1 is hydrogen, C.sub.1 -C.sub.4 -alkyl or phenyl,R.sup.2 and R.sup.3 are each hydrogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy,R.sup.4 is hydrogen or C.sub.1 -C.sub.4 -alkyl, andR.sup.5 is optionally substituted C.sub.1 -C.sub.10 -alkyl, C.sub.3 -C.sub.4 -alkenyl or C.sub.5 -C.sub.7 -cycloalkyl,by reacting dichloropyridines of the formula ##STR2## in a first step with an amine of the formula R.sup.5 -NH.sub.2 at from 10.degree. to 80.degree. C. in the presence of a base and of an inert organic diluent and/or water, then removing the diluent and thereafter, with or without prior intermediate isolation of the reaction product, comprises carrying out the second step in a melt at from 90.degree. to 165.degree. C. and at a pH from 3.5 to 6.5 using from 1.3 to 3 mol of aniline IV are used per mole of dichloropyridine II.
