You can prepare it by the catalytic hydrogenation of benzene, using high temp or pressure and a very active catalyst in my book it sez:

C6H6R (R being radical group e.g CH3) --> C6H11R
using H2 and Pt catalyst at high pressure

or there is a slightly more complex meathod, the "birch reduction" using sodium or lithium in liquid ammonia and adding ethanol protonises the benzene giving 1,4-cyclohexadiene a rarther complicated looking mechanism is here: http://fachschaft.cup.uni-muenchen.d...ion/birch.html
