実験手順
Sodium hydride (60%; 0.14 g) was added portionwise to an ice-cooled solution of 2-[3-(2,4-difluorophenylamino)-4-nitrophenyl]-2-methyl-1,3-dioxolane (1 g) in N,N-dimethylformamide. To the resulting mixture as added methyl iodide (1.7 g). The mixture was stirred at 0° C. for 30 minutes, poured into ice-water (50 ml) and extracted with ethyl acetate. The extract was washed with water, dried and evaporated. The oily residue was purified by column chromatography on silica gel (30 g) eluting with toluene to give an oil of 2-{3-[N-methyl-N-(2,4-difluorophenyl)amino]-4-nitrophenyl}-2-methyl-1,3-dioxolane (0.88 g).
