What syntax to use with sed c\

I know that I want to entirely replace line 3 in my file filename.txt. I have tried all sorts of variations of

sed 3,3,c\replacement stuff\ filename.txt with no success.

about the only thing that causes any reaction is

sed 3,3c\\ filename.txt
but it just prints out the whole file.

Your help would be much appreciated. I would like to run this from the command line and to run from within a shell script.

The text I actually want to put in line 3 is .run login.txt; just in case there are any peculiarities with dealing with any of those characters.

Many Thanks,

Susan
