Methanol → Methyl 4-chloro-3,5-dinitrobenzoate

Participants

Reaction Steps

Into a 250 ml round-bottomed flask equipped with a stirrer, thermometer and reflux condenser 74 g (0.3 mole) of 4-chloro-3,5-dinitro-benzoic acid, 128 g (4.0 mole) methanol and 14 g of concentrated sulfuric acid are introduced. The reaction mixture is refluxed under stirring for 8 hours, whereupon it is cooled to room temperature. The precipitated desired compound is filtered off, washed with 20 ml of cold methanol and dried. Thus 74.2 g of the desired compound are obtained, yield 95%, purity 99%.
