実験手順

A solution of 3-(2,4-difluorophenoxy)-4-nitrobenzoyl chloride (1.1 g) in dry ether (15 ml) was added dropwise to a stirred mixture of methylamine (40% in water; 2 ml) in water (8 ml) and ether (5 ml) at 5° to 8° C. The mixture was stirred for 30 minutes at 5° C. and for 30 minutes at room temperature. Precipitates in the mixture were filtered and washed with water and ether successively to give pale brown crystals of N-methyl-3-(2,4-difluorophenoxy)-4-nitrobenzamide (0.88 g).
