Yes, i have read that info. However, I want to first make lefetamine for the ease of the reaction, and then perhaps consider making the more potent analogue. And also, I want to get a dean stark trap before trying out the synth of that, as I would probably do it by reductivly aminating with diethanolamine, chlorinating and then reacting with cyclohexylamine (N-cyclohexylpiperazine is pretty expensive).
