As far as my interpretation of the rule that is totally fine. Salting out a freebase technically isn't creating or modifying molecule.
It is somewhat up to individual mods and their specific sub-forums. Their interpretation of what the word synthesis constitutes might be different than others. Some mods honestly don't even recognize synthesis discussion, some would allow a little more detail than others for various reasons. I
am a chemist so I am pretty sensitive and can recognize it and the potential for it pretty quickly. For that reason I am a bit more strict than some. There's been times I saw a discussion evolving and a question pops up that is right on the edge. There have been times that ignored it, I've come back 6 hours later and now there are users describe the exact steps they took to make a drug.
Like if I was mod of CD, i personally wouldn't even allow conversion discussion of delta 9 THC to delta 8 THC because even though the change is minor like flipping a double bond around a ring, it is modifying and changing one drug to a different drug with different effects/receptor affinities etc.. Even a minor chemical modification can require dangerous chemicals and skills/experience doing actual chemistry.
We don't want bluelight to become a place that people come to share specific information like that because (I hope you will agree with me here) not everyone has the knowledge or capability to do certain chemistry safely or legally even if they are super enthusiastic. We also think it's a bad look and tends to attract users that are interested in only that kind of information. We really don't want the forum to be flooded with that kind of discussion because that is way beyond what harm reduction (the ultimate focus and goal of the forum) actually is. In fact it can cause serious harm in multiple different ways. That's why we limit it.
Personally I want (some) people to make their own drugs and I hope you do actually create the strange cannabinoid you designed. Once you do it, we'd love to hear any information/experience you have regarding it's effects (good and bad) and again, how to use it safely.
This is a great thread where a user designed, created, and tested completely novel drugs himself, and then shared his experiences with those drugs. I think he actually did include synthetic notes in his overall writeups, but he chose to omit those aspects on bluelight itself.

I also posted this years ago, and though it's not the best SOP I ever wrote it's an example of what is also allowed.
So I'm actually getting kicked out of my house for making a very similar post a while back. I developed a process to isolate Mitragynine, and my roomate was in the process of selling the process to a company for a lot of money. I didn't really feel comfortable with the situation, so I released the it online for free for everyone. I ended up deleting the posts, but i might as well repost it. Oddly I posted it in R/ Kratom and the moderators deleted the post, I suspect because they have their own kratom companies and don't want people to know this information. So I'm putting it here...
