We investigate the reaction $ \pi^- p \rightarrow D^- \Lambda_{c}^{+} $within the generalized parton picture. The process is described by ahandbag-type mechanism with the charm-quark mass acting as the hard scale. Asin the case of preceding work on $\bar{p} p \rightarrow \bar{\Lambda}^-_c\Lambda_{c}^{+} $ we argue that the process amplitude factorizes into one forthe perturbatively calculable partonic subprocess $\bar{u} u\rightarrow \bar{c}c$ and hadronic matrix elements that can be parameterized in terms ofgeneralized parton distributions. Modeling the generalized parton distributionsby overlaps of (valence-quark) light-cone wave functions for the hadronsinvolved, we obtain numerical results for unpolarized differential andintegrated cross sections as well as spin observables. Our approach works wellabove the production threshold ($s \gtrsim 20 $GeV$^2$) in the forwardhemisphere and predicts unpolarized cross sections of the order of nb, afinding that could be of interest in view of plans to measure $ \pi^- p\rightarrow D^- \Lambda_{c}^{+} $ at J-PARC.
