If the MDP2P didn't react to form the imine, then when it went through the Al/Hg it would have formed MDP2Pol. Let's hope that didn't happen. But what it sounds like to me is that you got MDMA freebase, but when you tried to gas, you didn't dry everything properly, and so the MDMA*HCl formed a red tar with the water. Just do an acid/base, then gas again, this time with proper drying, you should get most if not all of your product back. Or you could just extract the toluene with some HCl solution, and the evap down to the red tar, then add some acetone, and you would get your crystals. But if you try it that way, you won't really get as pure of a product. It's up to you. But I'm reasonably confident that the product you have now will store fine until you have a chance to try and rescue it.
