Nonleptonic B to charmonium decays generally deviate from the factorization predictions. We study rescattering effects mediated by intermediate charmed mesons in this class of decay modes and, in particular, we consider B
– → K
–
h
c
with h
c
the J
PC
=1+–
meson, relating this mode to B
– → K
–
χ
c0. We find
large enough to be measured at the B factories, hence this process could be used to study the poorly known h
c
.
