Procedure

([3-(methylsulfinyl)-3-(methylthio)cyclobutyl]oxymethyl)benzene (2.4 g, 0.0089 mol) was dissolved in Et2O (40 mL) and 35% perchloric acid (1.8 mL) was added. The resulting mixture was stirred at rt overnight. To the reaction mixture was added solid NaHCO3 and MgSO4 and stirred for a while. The insoluble solid was filtered off. The filtrate was concentrated and purified with combiflash (silica gel, 100% dichloromethane) to give the desired product (0.7 g) as light yellow oil. LCMS calculated for C11H13O2(M+H)+: 177.1. Found: 177.3.
