  We study the deconfinement transition line in QCD for quark chemical
potentials up to $\mu_q \sim 5 T$ ($\mu_B \sim 15 T$). To circumvent the sign
problem we use the complex Langevin equation with gauge cooling. The plaquette
gauge action is used with two flavors of naive Wilson fermions at a relatively
heavy pion mass of roughly 1.3 GeV. A quadratic dependence describes the
transition line well on the whole chemical potential range.
