Abstract	We present the results of a study of exclusively reconstructed 𝐵 → 𝜋^−ℓ^+𝜈_ℓ decays, where ℓ is an electron or a muon. Complementary 𝐵 meson is reconstructed using the Full Event Interpretation algorithm. We take a piece of MC as a data and using an independent second MC sample try to analyse the method and its implications. We then try to make an estimate of the possible future Belle II analysis in terms of its performance and accuracy in measuring the branching fraction.
