Versuchsvorschrift

To a mixture of 5.00 g (0.021 mol.) of 2-[4-(1,1-dimethylethyl)phenoxy]-1,1-dimethoxyethane and 60 ml of acetic acid, there was added 6 ml of hydrochloric acid (36N) and the reaction mixture was stirred at room temperature for one hour. Then the reaction mixture was poured into 300 ml of cold water and filtrated quickly to recover a resultant white precipitate. The precipitate was obtained as a wet cake of 2-[4-(1,1-dimethylethyl) phenoxy]acetoaldehyde without being dried too much and was quickly used in the next step of the production procedure.
