Participants

Reaction Steps

A mixture of 4-[5-(4-Bromophenoxy)imidazol-1-ylmethyl]-1-(6-chloropyrazin-2-yl)-1H-pyridin-2-one (79 mg, 0.17 mmol) and zinc cyanide (12 mg, 0.1 mmol) in DMF (1 mL) was purged with argon for 5 min. A solution of tetrakis(triphenylphosphine)palladium(0) (20 mg, 17 μmol) in DMF (0.5 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, concentration of appropriate fractions, and trituration of the residue with anhydrous ether provided the titled compound as white solid.
