Procedure

A mixture of 1-{4-[5-(4-bromophenyloxy)imidazol-1-ylmethyl]-phenyl}-1H-pyridin-2-one (145 mg, 0.35 mmol) and zinc cyanide (24 mg, 0.2 mmol) in DMF (3 mL) was purged with argon for 10 min. A solution of tetrakis(triphenylphosphine)palladium(0) (40 mg, 35 μmol) in DMF (1 mL) was added. The resultant mixture was stirred under argon at 80° C. overnight, and concentrated under vacuum. The residue was subjected to column chromatography on silica gel eluting with 1:1 v/v 5% methanol in chloroform and chloroform saturated with ammonia gas. Collection and concentration of appropriate fractions provide the titled compound as white solid.
