The invention provides a process for preparing 2-pyridylalkylamines, substituted in one of the 3- or 5-positions by bromo and in the other by C.sub.1-4 alkyl, by reacting an appropriate C.sub.1-4 alkyl substituted 2-pyridylalkylamine with an electrophilic brominating agent. Said 2-pyridylalkylamines are useful as intermediates in the synthesis of compounds useful as histamine H.sub.1 -antagonists.
