	Hi there, Is it a good idea to rinse methylamine.Hcl with acetone after recrystalisation with Butal alcohol? Will any leftover alcohol interfere with Al/Hg or Borohydride reductions? Mayby I need to vacuum dessicate longer. I can't stand that Butal stench. Always knocks me out when opening the dessicator. Thanks, FF.

	Instead of acetone, wash with ether, CH₂Cl₂ or CHCl₃. MeNH₂.HCl is both inert to and insoluble in them all. Acetone may form an imine with MeNH₂.HCl so I don't reccommend that. Aside from smelling bad, butanol won't interfer the reductive amination.
