  We investigate the possibility to study the charmed baryon $\Lambda_c(2940)$
by kaon-induced reaction on a proton target. By assuming the $\Lambda_c(2940)$
as a $pD^{*0}$ molecular state with spin-parity $J^{p}=1/2^{\pm}$, an effective
Lagrangian approach was adopted to calculate the cross section, the $D^0p$
invariant mass spectrum and Dalitz plot of the $\Lambda(2940)$ production. The
total cross section of the $K^{-}p\to\Lambda_c(2940)D_s^{-}$ reaction is found
at an order of magnitude about 10 $\mu$b. By considering the sub sequential
decay $\Lambda_c(2940)\to{}D^0p$ with contributions from the $\Lambda_c(2286)$
and the $\Sigma_c(2455)$ as background, the $K^{-}p\to{}D_{s}^{-}D^{0}p$
reaction are studied. It is found that the $\Lambda_c(2940)$ is produced mainly
at forward angles. The $\Lambda_c(2940)$ signal is predicted to be significant
in the $D^0p$ invariant mass spectrum and the Dalitz plot of the
$K^{-}p\to{}D_{s}^{-}D^{0}p$ reaction. The results suggest that it is promising
to study the $\Lambda_c(2940)$ with high-energy kaon beam on a proton target in
experiment.
