Per the forum rules I don't think many people will help you with a DEA list 1 precursor.  If you have access to methylamine you should have access to the HCl salt, both are commercially available if you have the correct credentials.

Try not talking about DEA List I chemicals on an open forum to start.  Is your rotovap hot enough (I.E. think about what solvent you used).
