Reaction Steps

An aqueous solution of 40% methyl amine (61 mL, 0.71 mol) was added dropwise to a methanol solution (200 mL) of 2,4-difluoronitrobenzene (46.7 g, 0.29 mol) under ice cooling, and the mixture was stirred for 1 hour under the same temperature. The reaction solution was poured into ice water. Precipitated crystals were collected by filtration, followed by washing with water. The resulting crystals were dried at 50° C., thereby obtaining 47.6 g of a yellow, powdery target compound (yield: 95%).
