A search for the process e+e−→ D*0(2007) has been performed with the CMD-3 detector at the VEPP-2000 e+e−-collider. Two main decay modes of the D*0(2007) decay, D0π0 and D0γ, followed by D0 → K+π−π+π−are used in this analysis. With an integrated luminosity of 3.7 pb−1 collected at the center-of-mass energy Ec.m. =2006.62 MeV our preliminary upper limit is BD*0→e+ e− <1.6× 10−6 at 90%C.L.
