Participants

Reaction Steps

To a stirred and cooled (5° C.) solution of 10 parts of 4-[2-methyl-1-(1H-1,2,4-triazol-1-yl)propyl]-2-nitrobenzenamine and 6.7 parts of pyridine in 195 parts of dichloromethane was added a solution of 14.4 parts of 4-chlorobenzeneacetyl chloride in 39 parts of dichloromethane under nitrogen atmosphere. After stirring overnight at room temperature, the reaction mixture was washed with water, dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using a mixture of dichloromethane and methanol (99:1 by volume) as eluent. The eluent of the desired fraction was evaporated, yielding 11 parts (69.9%) of 4-chloro-N-[4-[2-methyl-1-(1H-1,2,4-triazol-1-yl)propyl]-2-nitrophenyl]benzeneacetamide (interm. 112).
