The basename command gets expanded by the shell you use *BEFORE* find
has a change to run.
You can try playing tricks with escaping the backquotes, which is
probably going to result very quickly in ugliness like \\\`foo\\\` or
you can use find to "generate" a list of filenames which will be
"processed" by the rest of the command-line to spit out the rename
commands, and feed them to sh(1) for execution, i.e.:
$ ls -l
total 0
-rw-rw-r-- 1 keramida wheel - 0 Aug 31 18:33 koko.dist
-rw-rw-r-- 1 keramida wheel - 0 Aug 31 18:33 lala.dist
$ find . -name \*.dist | \
awk '{ printf "mv \"%s\" `basename \"%s\" .dist`\n",$0,$0; }'
mv "./lala.dist" `basename "./lala.dist" .dist`
mv "./koko.dist" `basename "./koko.dist" .dist`
$ find . -name \*.dist | \
awk '{ printf "mv \"%s\" `basename \"%s\" .dist`\n",$0,$0; }' | sh
$ ls -l
total 0
-rw-rw-r-- 1 keramida wheel - 0 Aug 31 18:33 koko
-rw-rw-r-- 1 keramida wheel - 0 Aug 31 18:33 lala
