Reaction Steps

5.0 g (0.00194 mol) of 3-amino-4-benzyloxybenzene acetate are mixed under a nitrogen atmosphere in 15 ml of methylene chloride, and 3.3 ml of triethylamine (0.0236 mol) and 3.3 ml (0.0245 mol) of 1-butansulfonyl chloride are added thereto. The mixture is stirred at ambient temperature overnight and afterwards at 30° C. for 4 hours. Washing with water is carried out, the two phases are separated, the organic phase is dried over sodium sulfate and filtered, and the solvent is evaporated under reduced pressure. Purification is carried out by chromatography on a column of silica gel, elution being carried out with a cyclohexane/ethyl acetate=9:1 mixture. The title compound is obtained.
