We report the observation of a narrow charmoniumlike state produced in exclusive decay process B+/--->K+/-pi(+)pi(-)J/psi. This state, which decays into pi(+)pi(-)J/psi, has mass 3872.0+/-0.6(stat)+/-0.5(syst) MeV, value that is very near M(D0)+M(D(*0)) threshold.

We study the Dalitz plot of decay D(+)-->K(-)pi(+)pi(+) with a sample 15090 events from Fermilab experiment E791. Modeling amplitude as coherent sum known Kpi resonances and uniform nonresonant term, we do not obtain an acceptable fit.
