i was trying to make 2cb this days , at the last stage after bromination , i add NAOH to make 2cb go to the toluene layer (that added a bit later) , the toluene is sucked out and supposed to generate 2cbHCL when adding hcl , but instead only a black goo is generated that sinks at the bottom , i tried taking only the most concentrated toluene , from the top , and only trying to generate in it (thinking higher concentration will be easier to generate salt , and one had this problem that the drug just doenst want to generate salt in the solvent ?
