Versuchsvorschrift

A mixture of 818 mg (1.82 mmol) of 4-benzyloxy-3-(N-(tert-butoxycarbonyl)-N-(methylsulfonyl)amino)-1-((2S)-2,3-epoxypropoxy)benzene and of 450 mg (1.82 mmol) of ethyl trans-4-[4-(benzylamino)cyclohexyl]benzoate in the base form is heated at reflux in 15 ml of absolute ethanol for 16 h. The mixture is cooled, 3 ml of a saturated ethanolic hydrochloric acid solution are added thereto and the mixture is heated at 50° C. for 6 h. The solvent is evaporated and the residue is taken up with a mixture of 50 ml of a saturated sodium bicarbonate solution and 50 ml of ethyl acetate. The organic phase is washed with a saturated aqueous NaCl solution. The organic phase is dried and filtered, and the solvent is evaporated under reduced pressure. The crude product is purified by chromatography on a column of silica gel, elution being carried out with a methylene chloride/methanol/NH4OH (95/5/0.5) mixture. The title compound is obtained in the form of a white solid. [M+H+]=687.
