Versuchsvorschrift

3-Chloroperbenzoic acid (0.07 g) was added to a stirred solution of ethyl 6-(phenylthiomethyl)-3-ethyl-2-methoxybenzoate (Intermediate 19, 0.315 g) in DCM (5 ml) and the resultant mixture was stirred at room temperature overnight. The solution was evaporated to dryness and the residue was purified by chromatography on silica, eluting with a mixture of ethyl acetate and cyclohexane with a gradient of 0-100% to give ethyl 6-(benzenesulphinylmethyl)-3-ethyl-2-methoxybenzoate (0.095 g) as a clear gum.
