Thanks fellow bees for all the help:)
SWIM prepared anhydrous meam in cold methanol, it was weighing to 320g(100g scale dream), and suddenly, it became 290g. SWIM thought about suck back, but didn't notice it.
SWIM went on to add meam.hcl, dissolving all in cold methanol(the same batch), added NaOH to the solution to generate meam gas, on a 250mmol scale. Filtered the salt produced. Water was not removed.
Work up as the article stated, yield was not good, crystal clear solution was obtained after vaccuum distillation. Product tested good with 3 human object. Only problem was that the coming down gave SWIM some fever, as high as 38C(never experienced before in SWIM's 8 years of taking). Some valium helped though.
