Reaction Steps
According to the above procedure, a 2-halobenzoic acid is reacted with a phenol preferably in the presence of a base such as potassium carbonate and in the presence of cuprous iodide and copper bronze. The resulting 2-phenoxybenzoic acid is cyclized by treating with acid for example polyphosphoric acid. The resulting xanthone is reduced, for example using sodium amalgam in ethanol, to give the xanthydrol.
