It does not work because

1) The character ' introduces an OCTAL constant to TeX.  So
you should give the constants in octal.

2) You need to tell that these constants should be
interpreted as characters.

Here is what I use to get various "accented" characters; the
undersores (_) denote the actual 8-bit characters given as
octal to the right:

\catcode`\_=\active \def_{\`a}	% \340
\catcode`\_=\active \def_{\c C}	% \277
\catcode`\_=\active \def_{\c c}	% \347
\catcode`\_=\active \def_{\'e}	% \351
\catcode`\_=\active \def_{\"\i}	% \357
