Enclosing characters in single quotes preserves the literal value of each character within the quotes. A single quote may not occur between single quotes, even when preceded by a backslash.
Therefore, you need to terminate the quoted expression, insert the escaped quote, and start a new quoted expression. The shell's quote removal does not add any extra spaces, so in effect you get string concatenation.

logadm.conf
logadm.conf(4) File Formats logadm.conf(4)NAME
logadm.conf - configuration file for logadm command
SYNOPSIS
/etc/logadm.conf
DESCRIPTION
/etc/logadm.conf is the default configuration file for the log management tool logadm(1M). Comments are allowed using the pound character
(#) and extend to the end of line. Each non-comment line has the form:
logname options
where logname is the name of the entry and options are the default command line options for the logadm command. The name of the entry may
be the same as the name of the log file, or a log file name may be given in the options section of the entry. Long lines may be folded
using a backslash followed by a newline to continue an entry on the next line. Single or double quotes may be used to protect spaces or
alternate-style quotes in strings.
The preferred method for changing /etc/logadm.conf is to use the -V, -w, and -r options to the logadm(1M) command, which allow you to
lookup an entry, write an entry, or remove an entry from /etc/logadm.conf.
A full description of how and when /etc/logadm.conf is used and sample entries are found in logadm(1M).
