Leinster too strong for Toulouse in European Champions Cup semi-final
The Irish province scored 28 points during two periods when the French giants had a player in the sin-bin.
Leinster, bidding to equal Toulouse's record of five European crowns, scored three tries in 10 first-half minutes, two by Jack Conan, to stay well on course for the final which will see them back in front of a 'home' crowd at the Aviva on May 20.
Toulouse were still in touch at 27-14 behind at half-time thanks to tries by Pita Ahki and Emmanuel Meafou.
But despite a penalty by France's Thomas Ramos and a late try by England's Jack Willis, Toulouse were made to suffer for Rodrigue Neti's sin-binning, during which Josh Van der Flier and replacement Jason Jenkins both crossed for tries.
Ross Byrne's fourth-minute penalty gave Leinster an early lead, but Toulouse responded with the first try of the match.
Ramos's excellent 50-22 kick from Ramos gave Toulouse, whose side featured star France scrum-half Antoine Dupont, field position before centre Ahki capitalised on a three-on-two overlap to score in the left corner.
Following Byrne's second penalty, Toulouse were hit hard when centre Pierre-Louis Barassi hobbled off, with Dupont moving tio fly-half, and Ramos was yellow-carded for a deliberate knock-on.
Conan barged over from a pass by Ireland team-mate Jamison Gibson-Park pass, and the No 8 had a second try after selling a dummy to Juan Cruz Mallia.
Byrne converted both scores for a 20-7 lead and Toulouse then helped Leinster go further ahead when a mistake at a maul - replacement Paul Graou's pass hit Willis in the face - paved the way for Dan Sheehan's 25-metre try.
Van der Flier, on his return from an ankle problem, went over for Leinster's fourth try from a driving maul and victory was all but assured before Willis crossed for a consolation score late on.
Leinster will now face either La Rochelle, the team that beat them in last season's final, or Exeter in this term's tournament finale.
