Abstract We measure the branching fractions for the decays $B^{0}\to D^{*-}e^{+}\nu_{e}$ and $B^{*0}\to D^{*-}\mu^{+}\nu_{\mu}$ using the first $8.70 \pm 0.09 fb^{-}$ of data collected by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+ e^-$ collider using the decays $D^{*+}\to D^0 \pi^+$ and $D^0\to K^-\pi^+$.
