Procedure

30.0 g (63.8 mmole) of 2-[(2R)-(3,4-dichlorophenyl)-4-(3,4,5-trimethoxybenzoyl)morpholin-2-yl]ethanol [prepared as described in step (d) above] were dissolved in 500 ml of methylene chloride. 11.5 ml (83.0 mmole) of triethylamine and 5.93 ml (76.6 mmole) of methanesulfonyl chloride were then added, in that order, to the mixture, whilst ice-cooling, and the mixture was stirred at room temperature for 2 hours under a nitrogen atmosphere. The reaction mixture was then diluted with methylene chloride and washed with 1 N aqueous hydrochloric acid, and then with a saturated aqueous solution of sodium chloride, after which it was dried over anhydrous sodium sulfate. The solvent was removed by distillation under reduced pressure, and the resulting residue was purified by silica gel column chromatography, using a gradient elution method, with mixtures of hexane and ethyl acetate ranging from 1:4 to 1:9 by volume as the eluent, to give 34.8 g of the title compound.
