    摘要: A method for the synthesis of serinol and serinol derivatives substituted at the nitrogen atoms by reacting a lower 1,3-dialkoxy-isopropyl halide with ammonia or an amine to form a 1,3-dialkoxy-isopropylamine and then removing the ether groups by heating with a hydrogen halide acid. The method allows the production of serinol and serinol derivatives using inexpensive starting materials in a simple manner and obtaining a high purity product which is free of interfering isomers. Novel compounds obtained by the method which are useful as pharmaceutical intermediates, X-ray contrasting agents and cytostatic or psychopharmacological drugs are also disclosed.

    摘要: The invention relates to a process for preparing o-phenylenediamine. According to the invention 1,4-dichlorobenzene is nitrated to give 2,5-dichloro-nitrobenzene which is then reacted with an aqueous ammonium hydroxide solution and the 4-chloro-2-nitraniline obtained is subjected to catalytic hydrogenation to afford the end product which can thereafter be separated.The process according to the invention can be accomplished with a total yield of about 90% related to the 1,4-dichlorobenzene starting compound.o-Phenylenediamine is a valuable intermediate for instance in the synthesis of plant protecting agents and heat-resistant polymers.
