Procedure
The product of Example 9 was heated under reflux with pyridine chlorhydrate for 10 minutes then the reaction mixture was added to water. On recrystallisation of the resulting precipitate from a mixture of water and alcohol, crystals of 1-phenyl-2,2-di-(2,3,4-trihydroxyphenyl) ethylene having a melting point of 142° - 143° C were obtained. ##STR10##
