In the paper, we discuss the possible interpretation of the $J^P=1/2^{-}$ singly charm pentaquark as hadronic molecules. With the effective Lagrangian method, we further analyze the production properties of singly charm pentaquark from decays of $B$ meson, including strong coupling constants and production branching ratios of the charm pentaquark. Our numerical results show that the branching ratio of production of pentaquark from $B$ meson can reach to order of ${10}^{-6}$.
