The reaction mixture was stirred for about 15 hours at room temperature, diluted with 1.2 liters of water and acidified with acetic acid, and the product was filtered off. 36 g (94% of theory) of 5-(2,6-dichloro-4-trifluoromethyl-phenoxy)-2-nitro-benzyl alcohol, of melting point 143° C., were obtained.
