摘要:
The invention relates to a method for synthesizing 3,5-dichloroanisole from 1,3,5-trichlorobenzene, which comprises:a) the reaction between 1,3,5-trichlorobenzene and a methanolate of an alkaline or alkaline-earth metal in a first solvent chosen from among dimethylsulfoxide and 1,1,3,3-tetramethylurea;b) the precipitation of the product resulting from step a) in a second solvent which is not included among substances considered carcinogenic, mutagenic and/or toxic for reproduction by Regulation (EC) n° 1272/2008 of the European Parliament and of the Council of 16 Dec. 2008; thenc) the recovery of the precipitate thus obtained.Application: synthesis of 1,3,5-triamino-2,4,6-trinitrobenzene of which 3,5-dichloroanisole is an intermediate product.
