Procedure
17.2 g (105 mmol) CDT are added to a mixture of 20.0 g (100 mmol) (S)-1-(4-bromophenyl)-ethylamine and 17.6 mL (125 mmol) TEA in 300 mL dichloromethane at 0° C. Stirring is continued for 15 min at 5° C. After that time, the solvent is removed in vacuo and taken up in 50 mL methanol. 33.4 mL (180 mmol) sodium methoxide in methanol (30%) are added and stirring is continued for 48 h at rt. After that time, the solvent is removed in vacuo, the residue is taken up in ethyl acetate and washed with sat. KHSO4-solution (2×) and water. The organic layer is dried over magnesium sulphate and the solvent is removed by evaporation.
