Abstract

Compounds of the formula <FORM:0939270/IV(a)/1> where X is chlorine or bromine, are prepared by treating a compound of formula <FORM:0939270/IV(a)/2> with hydrogen at normal pressure and room temperature in the presence of a noble metal catalyst and a substantially equimolar amount of an inorganic or organic base, e.g. an alkali metal hydroxide or an amine. A preferred catalyst is palladium. In examples in which X is chlorine, iminodibenzyl is obtained as a by-product, and is isolated, after fractional distillation of the product, by crystallisation from methanol; or the desired fraction is reacted with acetyl chloride, the 5-acetyliminodibenzyl is separated from the 5-acetyl3-chloro-iminodibenzyl by fractional crystallisation, and the latter hydrolysed to 3-chloroiminodibenzyl. The compounds of formula I react with dialkylaminoalkyl halides to give medicinal compounds, such as 5-(g -dimethyl-aminopropyl)-3-chloro-iminodibenzyl. Specification 777,546 also is referred to.
