Problems With /replaceitem Command

I’m working on the KitPVP part of my server again. I’m trashing the part about buying the kits. All of them will be free. I’m trying to use /replaceitem to get the players their kits, but I have a few problems. I’m trying to get a leather tunic on the user which is dyed, named "Brute’s Body", and enchanted. This is what I’ve tried:

replaceitem entity @p slot.armor.chest leather_chestplate 1 0 {display:{color:7514398,Name:Brute's Body},ench:[{id:0,lvl:4},{id:34,lvl:10}]}

When I try this, it says it replaced that slot with "leather chestplate" but then it doesn’t. Does anyone know how to fix this?

replaceitem entity @p slot.armor.chest leather_chestplate 1 0 {display:{color:7514398,Name:"Brute's Body"},ench:[{id:0,lvl:4},{id:34,lvl:10}]}
