Come on folks! Have some pride please ;)
Sludge does not equal quality drugs. If you engage in a lengthy and expensive synthesis of a compound, do it properly. It's very little extra work really!
Instead of gassing, I'd suggest you do it as described here: Post 513755 (https://www.thevespiary.org/talk/index.php?topic=10164.msg51375500#msg51375500)

You simply need to basify, extract with toluene (or similar) and follow the writeup. You'll have a very minimal decline in yeild and wont have to worry about over acidifying etc!
Have a nice weekend,
