Beschreibung
Zusammenfassung:	The invention relates to a method for the preparation of 1,8-dihydroxy-10-acyl-9-anthrones, especially for use in the treatment of psoriasis, having the formula: where R is an alkyl group having 2-4 carbon atoms, by using as the initial material, 1,8-dihydroxy-9-anthrone and an acid chloride having the formula RCOC2, where R represents the same as above. In accordance with the invention, harmful benzene is replaced with, for example toluene; this replacing is possible because pyridine is replaced with 2,6-dimethyl pyridine.
