실험 절차

A solution of 10 parts of 4-[1-(1H-imidazol-1-yl)-2-methylpropyl]-2-nitrobenzenamine, 20 parts of ethyl β-oxobenzenepropanoate and 174 parts of benzene was stirred for 36 hours at reflux temperature. After cooling, the reaction mixture was evaporated. The residue was purified by column chromatography over silica gel using a mixture of dichloromethane and methanol (98:2 by volume) as eluent. The pure fractions were collected and the eluent was evaporated, yielding 7 parts (44.8%) of N-[4-[1-(1H-imidazol-1-yl)-2-methylpropyl]-2-nitrophenyl]-β-oxobenzenepropanamide; mp. 106° C. (interm. 96).
