has anyone ever chlorinated ephedrine with bleach?  what conditions would be needed for the reaction if it were possible.  I will test it out in the next few days if no one else has tried it.

I try to take my reactions on one at a time, but lately several reactions have attacked me at once.

But bleach is an oxidizing agent. Seems more likely that you will get methcathinone than chloroephedrine.
