UWe9o12jkied91di also forgot to mention that i used 10/100ml mix of hcl 36% and acetone to acidify i guess its either acetone or me adding acid to quickly... because at first it had rather nice color then went dark all of a sudden
draconic123I do not use acetone/hci mix, just 37% from freezer with dripping funnel, every 2-3 seconds 1drop...maybe you try this way one time
Jesse_Pinkman_dcm only or with acetone?
UWe9o12jkied91dAs solvent for 2b3c i used dcm or ethylacetate, i tried both with similar results...
Jesse_Pinkman_i meant for precipitation
Jesse_Pinkman_Ok I know its dumb, however just to be clear, so after acidification you take top layer or bottom layer to dry using dcm? Im confused

procedure sounds good, drip slower with good stirring
also be patient with just DCM, sometimes it decides to crash out in 2 min, sometimes it needs an hour stirring, acetone will help here I advise to use it (cold if poss.)
