Benzoic acid, 2,6-dinitro- → Methyl 2,6-dinitrobenzoate

참여 물질

반응 단계

2,6-Dinitrobenzoic acid (10.6 grams) is suspended in ether (125 ml.) at 0°C. 1-Methyl-3-p-tolyltriazine (8.2 grams) in ether (75 ml.) is added dropwise to the stirred reaction mixture in an ice bath. The reaction mixture is stirred at 0° for 1 hour and at room temperature for 1 hour. The reaction mixture is diluted to 1 l. with ether and the insoluble product collected by filtration. Recrystallization from methanol gives colorless crystals (3.65 grams, melting point 150°-151.5°). An additional 4.1 grams of product are obtained from the filtrate.
