Crystalizing Tryptamines can be very tough. If you can't vacuume distill, and you don't have a seed crystal, it can be tougher still. I've heard tales of guys waiting for months or even years for crystalizations to take place. Your post was a while ago, but it is possible, that you still don't have crystals. Here are two possibilities, get rid of solvents, and try to crystalize a little from boiling water. Just heat it up and let it sit for awhile cool. Another possibility is forming a hydrochloride. Careful, indoles don't like strong acids. But, sometimes it is the the way to go. I once synthesised a tryptamine derivative, vacuume distilled it to purify it, and waited patiently for about a month, but to no avail. Completely pissed, I introduced said material to dropwise addition of cold concentrated HCL with stirring. Crystals formed immediatly. I rinsed um off real well, and later released the free base, by heating with sodium bicarbonate in H2O. The base solidified immediatly upon cooling. Primitive, but effective. The tryptamine involved was not DMT. So, don't risk burning up all of your product, its no gimmie. Also, watch that PH. As long as the free amine is gobbling up HCL, the 2 position on the indole ring should be pretty stable. Should the PH become very acidic, bad things might happen.
