A mixture of 2.74 g. of ethyl α-(2-chloro-5-nitrophenoxy)propionate, 0.77 g. of 70% aqueous solution of ethylamine and 15 ml. of ethanol was kept at room temperature for one night. The precipitate was separated by a filtration and recrystallized from a mixture of benzene-cyclohexane to obtain 2.5 g. of the object compound (melting point of 148° to 149° C.).
