The ALICE experiment has the ability to measure D meson production in different colliding systems. Charm production in proton proton collisions is an important tool to test pQCD calculations in a new energy domain. Its spectrum in heavy ion interactions is influenced by the formation of hot and dense QCD matter. A common procedure to study the characteristics and effects of this matter is to compare particle production in heavy ion and proton proton reactions. Here we present a pQCD-based energy extrapolation of ALICE D meson pp measurements at $\sqrt{s}=7$~TeV to $\sqrt{s}=2.76$~TeV, as a reference for the PbPb studies at this energy. The status of the $D^0 \rightarrow K^{-} \, \pi^{+}$ analysis in pp collisions at $\sqrt{s}=2.76$~TeV will also be described.
