The rare semileptonic decay B0 → ϕℓ+ℓ−, where ℓ is an electron or muon, is considered in the QCD Factorization approach. The differential branching fraction, partially integrated over the interval q2 = [1 GeV2, 8 GeV2] of dilepton invariant mass squared, is estimated. The systematic uncertainty up to 10% resulting from the choice of the B-meson distribution amplitude is determined. The purely perturbative contribution to the B0 → ϕℓ+ℓ− total branching fraction is found to be B ∼ 10−12 which suggests searches of the B0 → ϕμ+μ− decay in the four-muon events at the LHC collider.
