Best overlap: 8:00 AM to 2:00 PM in Brasília is 12:00 PM to 6:00 PM in Amsterdam.
Plan around 8:00 AM to 2:00 PM in Brasília, which is 12:00 PM to 6:00 PM in Amsterdam, to catch everyone during office hours. Amsterdam is 4 hours ahead of Brasília, but with 6 hours of common ground you can hold morning or afternoon meetings without anyone working odd hours. Note that Amsterdam follows daylight saving while Brasília stays put, so the times above drift by an hour seasonally.
