Al-Hilal opened the scoring from the penalty spot in the 4th minute through Salem Al-Dawsari.
After a difficult first quarter of an hour, Flamengo came back to score thanks to Pedro who, well placed to the right of the goal, sent the ball flat with his foot to fail in the small left net (20th).
The Saudi club inherited a second penalty at the end of the first half after the expiry of regulation time on a foul by Gerson who was, at the same time, excluded for a second yellow card.
Al-Dawsari doubled the bet (45th + 9).
At ten, the Brazilians failed to get back into the rhythm at the start of the second period.
Al-Hilal first missed some great chances in the 58th and 67th until a fine goal by Argentinian Luciano Vietto in the 70th minute who calmly adjusted his shot from a tight angle to deceive the Flamengo goalkeeper.
Pedro belatedly allowed the Brazilian club to go up to 3-2 (90th + 1) but too late to be able to hope to win.
Al-Hilal, the winner of the Asian Champions League, will now face in the final the winner of the other half opposing Real Madrid to Egyptian Al Ahly in Rabat on Wednesday.
