Do it the right way...
Definitely do the A/B wash. Wash your HCL wash (amine "dissolved" in the acidic aqueous phase) with xylene or toluene and NOT DCM and discard this layer that has the unreacted ketone.
Basify this acidic extraction with NaOH until pH 12 or so and extract MDMA base using DCM, Toluene, or Xylene.
Repeat until you have enough freebase until you can vacuum distil.
Distilling the freebase is the way to go, anything less is for amatuers.
