At 0° C., 47 mg (0.19 mmol) of metachloroperbenzoic acid were added to a solution of 113 mg (0.19 mmol) of methyl 4-{[1-(2-{2-[(4-cyclohexylbenzyl)oxy]phenyl}-ethyl)-6-methoxy-6-oxohexyl]sulfanyl}benzoate 187 in 25 ml of CH2Cl2. The mixture was stirred at 0° C. for 30 min, and the cooling bath was then removed and stirring, was continued at room temperature for 16 h. After the reaction had ended, the mixture was washed successively with saturated Na2SO3 solution, saturated Na2CO3 solution, saturated NaCl solution and water. The organic phases were dried over Na2SO4 and the solvent was removed. The product was purified chromatographically (silica gel, cyclohexane/ethyl acetate 2:1)
