Best overlap: 8:00 AM to 3:00 PM in Brasília is 11:00 AM to 6:00 PM in Edinburgh.
Shoot for 8:00 AM to 3:00 PM in Brasília; your Edinburgh colleagues will see that as 11:00 AM to 6:00 PM. Edinburgh is 3 hours ahead of Brasília, but with 7 hours of common ground you can hold morning or afternoon meetings without anyone working odd hours. For part of the year the maths changes: Edinburgh observes daylight saving, Brasília does not, shifting the overlap by an hour.
