We present calculation of the next-to-leading corrections to the hard coefficient functions which appear in the description of nonleptonic B-decays in the factorization approach. These corrections, together with radiative corrections to the jet function, represent the full next-to-leading contribution to the hard spectator scattering term in the decay amplitudes. Using obtained analytical results we perform estimates of B → ππ branchings fractions in the physical (or BBNS) factorization scheme. We have also found that imaginary part generated in the hard spectator scattering term is quite large compare to the imaginary part of the vertex contribution.
