実験手順
To a mixture consisting of 50 g of 2,4-dichloro-5-methanesulfonylnitrobenzene and 150 ml of methoxyethanol was added dropwise a methoxyethanol solution of potassium hydroxide (potassium hydroxide 14.6 g/methoxyethanol 150 ml) while keeping the temperature at -5° C. or below. The reaction was carried out at -2° C. for 30 minutes and the reaction mixture was neutralized by adding 4 ml of concentrated hydrochloric acid. The neutralized mixture was heated to 90° C, whereby a uniform solution was formed. After the solution was cooled to 70° C., 220 ml of warm water was added dropwise thereto. The resulting precipitated crystal was recovered by filtration and dried to obtain 2-methoxyethoxy-4-chloro-5-methanesulfonylnitrobenzene. Yield: 50 g (87%).
