You can also try to buy Bitcoins with Paypal and tranfer the Bitcoins to OKPay. There you can exchange them for fiat money again. I did it like this some time ago.
So its the same thing if we say that PP >>OKpay or PP>>BTC Because there is no such exchange with exchange money from PP to other currency due to pp chargeback. You can exchange your PP to BTC or other currency here in the currency exchange if you are a trusted member.
Now the second option left that MZ already posted above is the PP>>Bank>>OKPay
Edit:
There may be some online exchanges or person that exchange PP to other currency Plesase DONT GO FOR THESE because most probably they will scam or
you will scam them
