The observation of the decay B +→ψ(3770)K +, where the ψ(3770) was constructed in the D 0D̄ 0 and D +D - decay channels, was reported. The branching fraction for the decay was measured and a 90% confidence level upper limit was set for the decay. Data was collected at the Y(4S) resonance by the Belle detector at the KEKB asymmetric-energy e +e - collider. Candidate π 0 mesons were identified as pairs of non-charged-track-associated electromagnetic calorimeter clusters.
