Unfortunately, you cannot. The only way to receive a Purrloin with Prankster is to encounter a Liepard in the Hidden Grotto in Routes 5 & 9. They have a 30% chance to be a female, which is what you would need in order to breed a Purrloin with Prankster.
However, Liepard only have a 4% encounter rate in the Hidden Grotto in Route 5, and a 15% encounter rate in the Grotto on Route 9. Even more so, when a Hidden Grotto refreshes, there is still only a 20% chance that there will be a Pokemon in it.
So...um, happy hunting, and best of luck to you! However, you could always check the Trade Corner, if you'd rather the easier way! (Be sure to read their rules and guidelines before posting).
