I was introduced through email to the CTO of a small company through someone I formerly worked for, who is a good friend with this CTO. He offered to do a twenty minute call with me, framed in informal terms, which sounded like a regular phone interview. He mentioned that he thought he would have some free time the following day to call. I sent an email back with my phone number and available hours for a call--8 hours that mostly overlap with regular business hours--for the following two business days, and I didn't receive a call. I feel I may have communicated poorly, as I didn't try to schedule a particular time, but I also know this person is incredibly busy all the time. What is appropriate in include in an email to try to get the call scheduled?

I would say something along the lines of "really enjoyed our conversation" and "when is the best time for you to have a follow up conversation". Not much else or you may come across as either desperate or a pest.
Notice I said when is the best time for you (you being the exec in this case) to talk. Let the busy executive tell you what works for them, and you make the time work for you both.
Giving available hours is perfectly appropriate, but that leaves you with the (possibly unlikely) problem that they might not confirm a specific time, and you might then be expected to be available the entire period, or ask them to tell you when they'd call.
Proposing a specific time is not ideal if they might not be available at that time (if they say "I am available any time between X and Y", then it's reasonable to assume proposing any time during that period would be fine).
A good middle ground might be to do both:
I'm available from 8 AM to 4 PM. Shall we schedule it for 2 PM?
This allows them to pick another time if that time doesn't suit them, but does give a strong preference towards having an actual time scheduled.
Saying "what time works for you?" instead of proposing a specific time can achieve the same goal.
Although I wouldn't worry too much about potentially "doing scheduling wrong" - if they really want to talk to you, less than optimal scheduling techniques is unlikely to change or get in the way of that.
