How to escape quotes in cron?

Question

Ruby on Rails

I need to run a certain model on time.
I do it like this:

57 14 * * * bash -l -c 'cd /home/app/project/pervichka/current/ && bundle exec rails runner -e production "Whenever.update_complexes('72,74,76')"' > /dev/null 2>&1

But where the variable is passed, there are quotes that need to be escaped:
Whenever.update_complexes('72,74,76')
I tried to do this:
Whenever.update_complexes(\'72,74,76\')
How to properly escape quotes in cron?
