We use an effective Lagrangian approach to investigate the production of the anticharmed pentaquark state with the minimal quark content
in the
decay. In our calculation, the
is considered as the molecule state of the
in an S wave, and its production and decay occur via triangle loops at the hadron level. With the moderate model parameters, the computed results suggest that the branching fractions of
can reach approximately
. The possible decay modes
and
are also investigated. It is hoped that these predictions could be helpful in searching for the anticharmed-strange pentaquark candidates in future LHCb experiments.
