Noone will spoonfeed you with the info you request, as you need quite a lot of chemistry background to understand the answer.
1) First, the nitrogen atom is protected using any standard N-protection group which does not also add to the phenolic oxygens.
2) Then you methylenate the phenolic oxygens with any of the milder methods listed here:

3) Finally, the N-protection group is removed using standard methods.
There is no easier way than what I just listed above. Looking more closely at the molecule, the product would actually not be "X PPA" (presumably 3,4-Methylenedioxy-phenylpropanolamine), but rather 1-(3,4-Methylenedioxyphenyl)-2-amino-butan-1-ol...
