To a solution of 24.2 g. of 2-(3-phenoxyphenyl)-1,3-dioxolane in 120 ml. of methanol a solution of 41.6 g. of sodium hydrogensulfite in 120 ml. of water is added, and the reaction mixture is boiled until no traces of starting compound can be detected by thin layer chromatography. The reaction mixture is cooled, the precipitated crystals are filtered off, washed with a 50% aqueous methanol solution and dried at 60° to 80° C. 27 g. (89.5%) of 3-phenoxybenzaldehyde bisulfite are obtained.
