Procedure
To a mixed solution of (2RS,3SR)-3-(3,4-dichlorophenyl)oxirane-2-carboxylic acid (50.0 g) and 2-(benzylamino)ethanol (38.9 g) in THF (700 mL)-methanol (100 mL) was added 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (71.2 g), and the mixture was stirred at room temperature overnight. The reaction solution was concentrated, the residue was diluted with ethyl acetate, and the mixture was washed with saturated aqueous sodium hydrogen carbonate, water and brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (42.2 g).
