We provide a novel and useful process for preparing triphenyl-butene derivative. A process for the preparation of a compound represented by Formula (IV):
wherein R
1
is hydrogen or substituted or unsubstituted alkyl,
characterized by reacting a compound represented by Formula (V):
with a compound represented by Formula (VI):
wherein R
1
has the same meaning as defined above,
in the presence of 1) a polyvalent metal chloride, 2) a reducing agent and 3) an alkali metal salt and/or a substituted or unsubstituted phenol.
