That's not possible because PayPal and Amazon are competitor payment processors, they don't link together. You'll have to accept payments from Amazon sales with the methods Amazon outlines in their support documents. Probably a bank account.
"It can take up to five business days for the money to appear in your bank account after Amazon initiates a payment. ... Before we can pay you, you must provide a valid bank account as the Deposit Method in your seller account settings. We cannot make payments to a credit card or online payment system, such as PayPal."
