Im gonna try it next time.
I mean, I already had the mixture on column and doing the CHCl3
:MeOH before I asked here. But I slowly increased the amount of MeOH in mobile phase so it worked OK-ish (IMO much better then 1st time). THe thing is quite large amount of CHCl3
required. I will have MS next week. But I guess I will have to go even more polar because there is still quite a lot left on column.
At least I got some nice crystals of bis-substitued ligand from before
BWT you guys posted so many ideas I dont know If I will have enough time to try them all
