Interaction of the 30-300 keV electrons with whistlers in solar coronal loops is studied using a quasi-linear approach. We show that the electron-whistler interaction may play a dominant role in the formation of fast electron spectra within the solar flare loops with the plasma temperature <~107 K and plasma density <~1011 cm-3. It is found that Landau damping of whistlers provides weak and intermediate pitch-angle diffusion regimes of fast electrons in coronal loops. The level of whistler turbulence in the weak diffusion regime under flare conditions is estimated as ~10-7 of the energy density in the thermal particles. The `top - footpoint' relations between the hard X-ray flux densities and spectra are derived. The reason for a `broken' spectrum of the flare microwave emission is discussed.
