An easy way to make MDA from MDP2P is to first make the oxime by reacting the ketone with hydroxylamine-HCl. This can be done in good yields (>90%). See CA -55, 10595 for details.
The formed oxime is reduced by adding a 10 molar excess of sodium pieces to the oxime in anhydrous EtOH. See J. Chem. Soc. Perkin. Trans 2, -97, pp249-56 for a good procedure. This gave 3.2g MDA from about 4g oxime using 6g sodium and 50ml EtOH. If you're interested I can do a write-up on this...
