  Using the experimental upper bound on the neutron EDM and experimental result
on $b\rightarrow s\gamma$ branching ratio we have calculated CP asymmetry and
$\Gamma^{2HDM}(b\rightarrow s{\it{l^{+}l^{-}}})/\Gamma^{SM}(b\rightarrow
s{\it{l^{+}l^{-}}})$. It is shown that in the invariant dilepton mass $q^{2}$
region $(m_{\psi'}^{2}+0.2\; GeV^{2})<\;q^{2}<\;m^{2}_{b}$ the CP asymmetry is
maximal and quite detectable.
