Abstract
An improved process for the preparation of N-amino nitrogen heterocyclic compounds is disclosed and claimed. In an embodiment of this invention, a compound of the formula (VI) is prepared starting from the corresponding indole derivative by way of N-amination and subsequently forming an hydrazone by the reaction with a keto compound in a single step. Further reduction of the hydrazone and subsequent coupling with a pyridine compound affords the compound of formula VI or a suitable salt thereof. ##STR00001##
