실험 절차

A solution of ethyl 2-(4-acetyl-2-methylphenoxy)-2-methylpropanoate (intermediate 8, 37.33 g) in dichloromethane (650 ml) was treated with 4-toluenesulphonic acid (2.75 g) followed by m-chloroperbenzoic acid (60.5 g) and the mixture warmed to 40° C. and stirred under nitrogen for 19 hours. The cooled mixture was treated with dichloromethane (350 ml) and the resulting mixture added to aqueous potassium iodide (1000 ml, 10% solution). The organic layer was collected and washed twice with water and brine, then dried over sodium sulfate, filtered and the filtrate concentrated to give the title compound as an orange oil.
