Reaction Steps

To a stirred solution of 2-[4-(5-oxazolyl)phenyl]-2-methyl-1,3-dioxolane (711 mg, 3.08 mmol) in acetone (18 ml) and water (2.8 ml) was added pyridinium p-toluenesulfonate (116 mg, 0.46 mmol), and the mixture was heated at reflux temperature for 8 hours. The mixture was cooled down to room temperature, and concentrated in vacuo. The residue was dissolved in diethylether and washed with saturated NaHCO3 aqueous solution, brine, dried over MgSO4, and concentrated in vacuo. The compound was used for next reaction without purification.
