Reaction Steps
Under an inert atmosphere, 1.3 equivalents of mesyl chloride in 15 ml of dichloromethane are added dropwise to a solution of 0.16 mmol of the compound obtained in Step A and 2.8 equivalents of triethylamine in 1 litre of dichloromethane at 0° C. After stirring the mixture at ambient temperature for 4 days, a saturated aqueous solution of NaCl is added. After extraction, drying, filtration and concentration of the organic phase under reduced pressure, chromatography of the residue on silica gel (dichloromethane/ethanol: 97/3) enables the expected product to be isolated.
