Procedure

Mix 5.5 g (0.02 mol) of (S)-1-(3-methoxyphenyl)-N-methyl-N—((S)-1-phenylethyl)ethanamine (formula IV) with 12 ml N,N-dimethylformamide and 12.6 g (0.1 mol) of dimethyl sulfate at room temperature, heat the mixture to 60° C. for 24 hours. Let it cool to room temperature, and add 100 ml of ethyl acetate. A light yellow solid is produced. Filter and dry it to receive 5.7 g light yellow solid with a yield of 72%.
