I added a sleep because a continuous loop will eat your system for lunch.
Code:
while [ ! -d /xx/xx ]
do
    sleep 1
done
# we get here only when the /xx/xx directory comes into existence
cp filename filename.anton

so the cp filename filename.anto comes after the done

Alternative:
Code:
until [ -d /xx/xx ] 
do 
  sleep 1 
done 
cp filename filename.anto
