We use QCD sum rules to study the possible existence of a $D s\bar{D}^*+ D s^*\bar{D}$ molecule with the quantum number $J^P=1^+$. We consider the contributions of condensates up to dimension eight and work at leading order in $\alpha s$. We obtain $m {D sD^*}=(3.96\pm0.10) \GeV$ around 100 MeV above the mass of the meson X(3872%2
