How to loop named mobs in a radius around player

[iNuclearTNT]

wait 3 seconds
loop entities in radius 50 around player:
if {system.kitpvp.loopedminion.%uuid of entity%} is set:
kill loop-entity

EDIT:
Ignore the if {system.kitpvp.loopedminion.%uuid of entity%} is set:

I want to replace it with if loop-entity is named "&c%player%'s Skeleton": But I know that's not how you do it correctly
