ABSTRACT:
A synthesis procedure for the manufacture of byphenylimidazolyl-(1)-phenylmethane involves the reduction of 4-phenyl-benzophenone and subsequent reaction of biphenyl-phenyl-carbinol with imidazole. In a preferred form, there are two synthesis steps, the first step being the reduction of 4-phenyl-benzophenone to biphenyl-phenyl-carbinol being with sodium borohydride in the presence of alumina, and the second step being the reaction between biphenyl-phenyl-carbinol and imidazole assisted by microwaves, in the absence of any organic or inorganic solvents, obtaining a yield between 70 to 74% of pure product in a total reaction time of no more than three hours.
