The resulting solution is cooled to 0° C. and chloromethylmethylether (0.16 g, 2.0 mmol) is added at such a rate that the temperature does not exceed 5° C. After stirring the mixture for 2 hours at room temperature, the solvent is evaporated under reduced pressure and the product is purified by chromatography. The product is obtained in form of slightly yellow crystals, m.p. 114–115° C.
