Reaction Steps

The title compound was prepared from (trans), (trans)-1,2-dichloro-4-[4-(4-nitrophenyl)-1,3-butadienyl]benzene (15.42 g, 0.048 mol), Ra—Ni (1 g) at 20° C. to 26° C. (ΔP=19.3 psi) under a hydrogen atmosphere in THF (75 mL) and MeOH (75 mL) using the procedure described in Example 1, Step B. This procedure yield a solid, 10.97 g (0.037 mol, 78%) of the desired product. mp 50-52° C.
