  We have succeeded in the synthesis of Re-doped
$HgBa_{2}Ca_{n-1}Cu_{n}O_{2(n+1)+\delta}$ quickly by a sealed tube technique
with a bit of CsCl flux. Powder X-ray diffraction measurement revealed that the
single phases of Re-doped $HgBa_{2}CuO_{4+\delta}$ (Hg1201),
$HgBa_{2}CaCu_{2}O_{6+\delta}$ (Hg1212), and $HgBa_{2}Ca_{2}Cu_{3}O_{8+\delta}$
(Hg1223) formed in 4 h. The sample grains exhibited plate-like crystals with
the sizes of 20$\times$20$\times$1 $\mu m^{3}$ and the chemical compositions of
Hg1201, Hg1212, and Hg1223. The superconducting transitions were observed at 25
K for Hg1201, 122 for Hg1212, and 133 K for Hg1223 in the magnetic
susceptibility. These results indicate that the developed method is useful for
the fabrication of Hg-based superconducting wires.
