Imidazole → 1-[(4-Nitrophenyl)(phenyl)methyl]-1H-imidazole

Participants

Reaction Steps

To a stirred solution of 88.7 parts of 1-[chlorophenylmethyl]-4-nitrobenzene in 790 parts of acetonitrile were added 121.8 parts of 1H-imidazole. After stirring for 24 hours at reflux temperature, the reaction mixture was evaporated. The residue was taken up in methylbenzene. This solution was washed with K2CO3 (aq.), dried, filtered and evaporated. The residue was purified by column chromatography (silica gel; CH2Cl2 /CH3OH 98:2). The eluent of the desired fraction was evaporated, yielding 53 parts (53%) of 1-[(4-nitrophenyl)phenylmethyl]-1H-imidazole (interm. 42).
