実験手順

A solution of 3-(2,4-difluorophenoxy)-4-nitrobenzoyl chloride (2.2 g) in tetrahydrofuran (8 ml) was added dropwise to a stirred solution of dimethylamine (50% in water; 2 ml) in water (10 ml) at 5° C. The mixture was stirred for 30 minutes at 5° C. and for 1 hour at room temperature. The mixture was concentrated and extracted with chloroform. The extract was washed with water, dried, and concentrated under reduced pressure. The residue (2.4 g) was solidified with a mixture of hexane and ethanol to give pale brown powder of N,N-dimethyl-3-(2,4-difluorophenoxy)-4-nitrobenzamide (2.0 g).
