The previous replies all look wrong to me :-)

Your pdb file has atom names for hydrogens that are very old (so called
version 2 of the PDB format, which was retired many years ago.) The
simplest thing to do is to run pdb4amber with the --nohyd option to remove
all the hydrogen atoms. LEaP will then rebuild them with the correct names.

...hope this helps....dac
