Reaction Steps
Mix 7.9 g (0.02 mol) (S)-1-(3-hydroxyphenyl)-N,N-dimethyl-N—((S)-1-phenylethyl)ethanaminium iodide (formula VIII) with 180 ml of acetonitrile, 4.1 g (0.03 mol) of potassium carbonate, 3.6 g (0.03 mol) ethyl(methyl)carbamic chloride and 0.1 g of macrogol 400 at room temperature, heat the mixture to 60° C. and let it react for 12 hours. After cooling to room temperature, filter it and reduce the pressure to recover the solvent and receive 10.3 g of red-brown liquid to be directly used in the next reaction.
