Participants

Reaction Steps

To a stirring solution of Methyl 3-(benzyloxy)-5-(4-formylphenoxy)benzoate (30 g) (Intermediate 11) in acetone, Jones reagent was added drop wise at 0° C. until the brown color persists in the reaction mixture. After completion of the reaction mixture was diluted with water and extracted with DCM.
