You can't do that, at least not easy. Once VTP domain it is created cannot be removed.
The only way to remove it is to restore switch to default configuration - erase startup config and vlan.dat file. You can first save startup or running configuration (whatever you prefer) and than delete startup-configuration, vlan.dat and then reload switch (do not save changes prior to reload). Than after reboot you can paste saved configuration. Switch after restart by should be in server mode so it should receive VTP domain from other switches, so you can prior to do this remove it from other parts of network by shutdown ports and then configure switch in transparent mode so switch do not accept VTP domain when it is attached again to rest of the network.
