Reaction Steps

add 561 mg of anhydrous potassium hydroxide to a solution of 1.54 g of 4-amino-3-nitrophenol in 6 cm3 of N,N-dimethylformamide. Add dropwise, to the purple solution obtained, 2.4 g of 2-(bromomethyl)-1,3-dichlorobenzene in solution in 2 cm3 of N,N-dimethylformamide, without exceeding 20° C. After stirring the reaction mixture for about twenty hours at a temperature around 20° C., the reaction mixture is poured into 200 cm3 of water. The mixture obtained is extracted three times with 100 cm3 of ethyl acetate. The combined organic phases are washed five times with 50 cm3 of water, dried over magnesium sulphate, filtered and concentrated under reduced pressure (0.2 kPa). The residue is taken up successively in a 50/50 mixture of diethyl oxide and diisopropyl oxide, and finally drained, washed three times with 2 cm3 of diisopropyl oxide, then dried under reduced pressure in the presence of potassium hydroxide. We obtain 2.4 g of 4-[(2,6-dichlorobenzyl)oxy]-2-nitroaniline in the form of a white powder, which has the following characteristics:
