@WillD I need help clearing up a few steps ....

When you separate a free base of a-pvp in ethyl acetate (oil) (alpha-bromvalerophenone)

Do I now heat it up to 70c to evaporate the ethyl acetate off? ( if so how long for)

Then start to add acetone and hcl to bring ph5, then in freezer 12 hours?
.......

Or do I need to

1 Heat to 70c to evaporate ethyl acetate 2 then wash alpha-bromvalerophenone with water and soda solution? ( how do I do this, just mix alpha-brom with soda and water solution and separate????)


Then put spereated and washed alpha-brom in acetone and add hcl to ph5 and frozen 12 hours
