Can you explain what you're trying to do?

The pipe characters are necessary to define a concatenated list of
commands to :autocmd. The backslashes are line-continuation characters
to break up what would otherwise be a long line.

The easiest way to avoid both in this context is to define a function to
group the commands:

function! MyFunction() abort
...
endfunction

if has('autocmd')
autocmd BufLeave * call MyFunction()
endif
