The decay B+ to psi(2S) phi(1020) K+ is observed for the first time using data collected from pp collisions at sqrt(s) = 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 inverse femtobarns. The branching fraction of this decay is measured, using the mode B+ to psi(2S) K+ as normalization, to be (4.0 +/- 0.4 (stat) +/- 0.6 (syst) +/- 0.2 (B)) x E-6, where the third uncertainty is from the measured branching fraction of the normalization channel.
