A process is described for producing 2-chloroallyl isothiocyanate from 2,3-dichloro-1-propene by reacting the 2,3-dichloro-1-propene with a thiocyanate in the presence of a phase transfer catalyst, without diluent or in the presence of up to 15 percent by weight based on 2,3-dichloropropene and simultaneously in the presence of an excess of from 10 to 200 mol percent of 2,3-dichloro-1-propene based on the thiocyanate. A process starting from 1,2,3-trichloropropane is also described.

Method for producing 2-chloroallyl thiocyanate and 2-chloroallyl isothiocyanate

The present invention relates to a process for the preparation of pure 2-chloro-5 -chloromethylthiazole by distillation in the presence of oligomeric polyethers.

Method for purifying 2-chloro-5-chloromethylthiazole

The present invention relates to a novel process for preparing known benzofuranone oximes, and to a novel process for preparing known benzofuranyl alkanoates which are used as intermediates in the synthesis sequence.

Method of production of benzofuranone oximes

The invention relates to a novel process for preparing 2-chloro-5-chloromethylthiazole by reacting 2-halogenoallyl isothiocyanates with a chlorinating agent.

Process for preparing 2-chloro-5-chloromethylthiazole

(Quinolin-2-yl-methoxy)phenylacetic acids are known as inhibitors of enzymatic reactions in the context of arachidonic acid metabolism. Enantiomerically pure (quinolin-2-yl-methoxy)phenylacetic acids can be prepared in a simple manner and in high purity and yield by diastereoselective alkylation of corresponding (quinolin-2-yl-methoxy)phenylacetic acid menthyl esters and subsequent specific removal of the ester radical with acids.
