A search for the decays of the meson to is performed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb-1 collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. No signal is found and an upper limit, at 95% confidence level, is set, $$\frac{fc}{fu}$$ × $$\mathscr{B}$$ ( → ) < 3.6 × 10-8 in the kinematic region m($$p\bar{p}$$) < 2.85 GeV/c2, pT(B) < 20 GeV/c and 2.0 < y(B) < 4.5 where $$\mathscr{B}$$ is the branching fraction and fc(fu) is the is the fragmentation fraction of the b quark into a Bc+(B+) meson.
