The possibility of synthesizing a doubly magic superheavy nucleus, {sup 298}114{sub 184}, is investigated on the basis of fluctuation-dissipation dynamics. In order to synthesize this nucleus, we must generate more neutron-rich compound nuclei because of the neutron emissions from excited compound nuclei. The compound nucleus {sup 304}114 has two advantages to achieving a high survival probability. First, because of low neutron separation energy and rapid cooling, the shell correction energy recovers quickly. Secondly, owing to neutron emissions, the neutron number in the nucleus approaches that of the double closed shell and the nucleus attains a large fission barrier. Because of these two effects, the survival probability of {sup 304}114 does not decrease until the excitation energy E{sup *}=50 MeV. These properties lead to a rather high evaporation residue cross section.
