AB Evidence is presented for the decay B+c → J/ψ3π+2π− using proton-proton collisiondata, corresponding to an integrated luminosity of 3 fb−1, collected with the LHCbdetector. A signal yield of 32 ± 8 decays is found with a significance of 4.5 standarddeviations. The ratio of the branching fraction of the B+c → J/ψ3π+2π− decay tothat of the B+c → J/ψπ+ decay is measured to beB (B+c → J/ψ3π+2π−)BB+c → J/ψπ+  = 1.74 ± 0.44 ± 0.24,where the first uncertainty is statistical and the second is systematic
