Converting from a stem word to any other word nearly always changes pronunciation, even if only stress intonation.

E.g. noun to adjective.

ATtribute > aTRIButed
CONduct > conDUCted
EXtract > exTRACted

Those are examples of a change in word stresses. Which happen in Dutch as well.
The example of dynasty and dynastic, is a change from an short i, to long y.
For the example you listed to be analogous they'd have to be:
Ah-tribute > Aa-tributed
Con-duct > Coon-duct
Ex-tract > Eex-tract

Or to reverse engineer your examples on dynasty/dynastic:
DInasty > diNAStic rather than DInasty > DYnastic.
