Versuchsvorschrift
The process of the present invention comprises reacting phenyl lithium with 1,8-dihydroxy anthraquinone in the presence of an anhydrous organic solvent, such as tetrahydrofuran, to form 1,8,10-trihydroxy-10-phenyl-9-anthrone which is then reduced with a reducing agent so as to produce 1,8-dihydroxy-10-phenyl-9-anthrone.
