Reaction Steps

33.4 g of 2-chloro-1,3,5-trifluorobenzene and 200 ml of methanol saturated with ammonia gas at room temperature were sealed in a Teflon-coating autoclave and heated on an oil bath at 160° C. for 40 hours. After the reaction, the solvent and unreacted 2-chloro-1,3,5-trifluorobenzene were distilled off from the reaction mixture under reduced pressure, and the remaining mixture of a solid component and an oily component was extracted with ether to obtain an oily product in an amount of 31.7 g (yield of 2-chloro-3,5-difluoroaniline: 95% determined by GLC analysis).
