Procedure
94.8 g (0.40 moles) 1,5-dichloro-2,4-dinitrobenzene in 580 ml ethylene glycol is heated to 50° C. To the mixture is then very gradually added, with stirring, 50.4 g (0.60 moles) sodium ethylene glycoxide over approximately 6 hours. One hour after addition is complete, TLC (ethyl acetate) shows the reaction is complete. The heat is turned off and the mixture is allowed to cool to room temperature. The precipitated product is collected by vacuum filtration and is washed with water. The water causes additional product to precipitate in the filtrate. The product is dried in a vacuum oven at 50° C. Yield of the combined crops is 82.7 g (78.8%), m.p. 98°-100° C.
